FitRX Massage Gun Review – Cheap, But Massively Underperforming

Hey there! We recently got our hands on this FitRX massage gun, also known as Tzumi or ProFIT massage gun. You can find it in plenty of places, including Walmart, Macy’s, eBay, and Amazon. It’s all the same device, just with different names depending on where you look.

But even though it’s widely available, that doesn’t automatically mean it is a good device.

We picked it up for about $50, and while it seemed like a steal at first, we were quickly disappointed. This guy might look like the high-end Ekrin, but it definitely doesn’t perform like one. We realized this after putting it on our test drive and also dismantled it to check what’s inside.

So in this review, we’re going to cover all of its features. More importantly, we’ll explain why, in our opinion, this massager isn’t worth the investment and where it disappoints the most. But just so you know, we’re going to recommend some much better options at the end of this review.

FitRX Massage Gun Review

Tzumi FitRX Specifications

First Impressions

When we first got our hands on the Tzumi FitRX (or ProFit, depending on where you buy it), we were excited to see what this sub-$50 massage gun could do. We were hopeful that it would at least look and feel similar to the high-end Ekrin guns we’ve tested in the past.

The first thing we noticed was the carrying case. Hey, not bad! A good start for a budget massage gun. But then we opened it up, and our hopes were quickly dashed.

The FitRX just looks cheap. It’s made of flimsy plastic, and doesn’t feel like it’s put together very well. When we shook it from side to side, it felt like something was loose inside (and what’s inside, we’ll find out shortly.). Not a good sign.

The gun itself is all matte black, which we guess is fine, but it doesn’t do much to hide the fact that it feels like a cheap knockoff.

And don’t even get us started on the control button placement. It’s not where it should be – at the bottom of the handle. We’ve seen this in mini massage guns before, but in a full-sized gun? Come on. And when you do press the button, it makes a cheap click sound that just adds to the disappointment.

On the bright side, the FitRX does have a USB-C port, which is a nice touch.

Size, Weight, and Ergonomics

Let’s talk about the size, weight, and ergonomics of the ProFIT massage gun. When it comes to massage guns, size and weight are important factors that can greatly affect their performance.

So the biggest surprise of all is just how big this thing is. We were expecting something a bit more compact, but this gun is definitely on the larger side.

The FitRX is actually bigger than the high-end Ekrin B37 or B37S (those aren’t small by any means). It’s taller and thicker, but surprisingly light at only 1.8 lbs. That’s less than much smaller devices like the Ekrin 365, Sportneer D9 Elite, or even the Urikar Pro 2, which is also a large gun.

When we see a device that’s big but light, we know it probably won’t perform up to expectations. And in this case, our suspicions were correct (more on that later).

But the ergonomics of the FitRX are actually the best part of this device. The angled handle, just like in the Ekrin, adds an extra 1-2 inches when reaching the lower back, which reduces hand and wrist fatigue.

Plus, you can hold this device in a few different ways, which is always a plus. The rubber grip is also a nice touch, although we wish it extended all the way up instead of just in the middle.

Controls

The device only has one button, which is located at the bottom of the handle – a sign of a budget approach.

However, it’s simple enough to use with a long press to activate and a short press to change speeds.

There are no fancy LCDs or OLEDs, just a basic LED speed indicator.

While it’s not the most advanced control system out there, we can live with it.

Inside Look: Disassembling the FitRX

Curiosity about the FitRX’s large size yet light weight led us to wonder what’s going on inside (as a reference, you can read here about what a typical massage gun construction is like). We decided to crack it open and take a peek. Honestly, what we found was a bit of a letdown, again.

The build quality? Not great. It’s mostly cheap plastic parts in there.

One thing that really stood out was how the motor’s movement gets transferred to the massage heads — all done with flimsy plastic. Even the way the motor’s attached to the body is all plastic.

And get this, one part actually broke while we were taking it apart. That’s not a good sign, right?

What else did we see? There’s a tiny battery, hardly any electronics (so don’t expect any cool features or smart battery management), and zero effort in soundproofing. No anti-vibration pads, nothing to muffle the motor or mechanical noise.

Check out these photos and see for yourself. It’s pretty revealing:

Attachments

Let’s talk about the attachments that come with the Tzumi FitRX massage gun.

First, we have to admit that four attachments at this price point is a good deal. However, the quality is so-so.

Only one attachment, the ball head, is made of foam, and even that foam feels pretty firm. We know that foam like this can deteriorate over time, so it’s not the most durable choice. 

The other three attachments are all hard plastic. There’s:

• a fork head for muscles along the spine, 
• a bullet head for trigger points ^​2​, and 
• a flat head for larger muscle groups. 

While the fork and bullet heads are okay, we were disappointed by the flat head. It has a small diameter and feels like it’s from a mini device, not a full-size gun. All in all, the attachments are serviceable, but nothing to write home about.

Performance

In performance, we examine a device’s amplitude, stall force, and percussions per minute. And this is the worst part of this device.

Amplitude

This device has a measly 6mm of amplitude, or 6.27mm according to our high-precision caliper. Can you believe it? We sure couldn’t.

We’ve seen some low-amplitude guns in our day, but this one takes the cake for a full-size device.

As you can imagine, the lack of amplitude means that it doesn’t pack much of a punch when it comes to percussive hits. Instead, it feels more like a glorified vibrating massager.

But, don’t lose hope just yet, because vibrations can be effective for deep tissue if the device is able to rev very fast (usually above 3200 rpm). Plus, if the stall force is enough, you can press the device against the muscle without it slowing down, which can deliver a reasonably powerful treatment.

Sadly, the FitRX massage gun doesn’t have either of these features, so it’s not looking too good in the effectiveness department. We’re not ones to sugarcoat things, but we’re also not ones to give up hope entirely. Let’s see how it fares in the next section, shall we?

Percussions

Well, let’s face it: the FitRX / Tzumi massage gun is not a percussion powerhouse. Despite its promise of delivering 3200rpm, our tests show that it falls short, clocking in at a meager 2150-2880rpm.

That’s not going to cut it for those who are looking for a deep tissue massage. With such a low amplitude and intensity, it’s just not effective enough as an all-rounder. 

However, it’s not all doom and gloom. The device can still help alleviate sore neck and shoulder muscles, and can be used to warm up soft tissues and get the blood flowing ^​3​. But if you’re after a true deep tissue massage gun, the FitRX just isn’t going to be a worthy choice.

Stall Force

Stall force – the amount of pressure a device can withstand – is where it’s at when it comes to massage guns, and unfortunately, this one falls a bit short.

We hate to say it, but the FitRX stalls like a cheap mini gun. Even on the first speed, it slows down with the slightest pressure or contact with the skin. That’s just not going to cut it when it comes to deep tissue massage.

We’re talking a maximum performance of maybe 15lbs, which is pretty laughable for a device of this size. It’s Hypervolt Go 2 déjà vu, but the Go 2 is a mini device! But we’re not surprised after seeing the kind of motor powering this device. Even children’s toys can have more serious engines.

Noise

Well, it looks like the ProFIT massage gun doesn’t do well in the noise department either.

With a range of 59-68 dB, it’s definitely above average and not what you’d expect from a device with a low amplitude like this one.

Typically, lower amplitude devices are quieter, but that’s not the case here. The stroke length could be the culprit since longer strokes generally lead to more noise. But that’s no excuse for a 6mm stroke length to produce such a racket!

The real kicker is the rattling and the tractor-like sound it makes. It’s enough to make you think the thing is about to fall apart. And nobody wants that!

So, a massage gun with such a small motor and short amplitude shouldn’t be this loud, but the problem is elsewhere. This device lacks any soundproofing or anti-vibration pads. The interior is almost hollow, which does nothing but exacerbate the noise level.

Battery

Here too we only have some more not-so-good news. With only 2000 mAh, the battery’s not going to last as long as you might want it to. In fact, most mini guns have a bigger battery, which is a bit disappointing.

Take the Sportneer D9 Elite, for example, which has a 3350 mAh battery – that’s over a third bigger! And let’s not forget about the Urikar Pro 2, which has a 2600 mAh battery.

So, you can expect about an hour or two of battery life, maybe even less if you’re using high speeds. And let’s be real, this device stalls way too easily to be used on low speeds anyway.

But, the Tzumi massage gun does have one saving grace – the USB-C charging. Kudos for that! It’s just like the Ekrin 365, which we wholeheartedly recommend if you have an extra $100 to spend.

However, we’re skeptical about the long-term performance of the Tzumi, given what we sound inside and the quality of its parts. So, if you want better battery life, we recommend checking out some of the alternatives we mentioned above.

Price and Warranty

What about the price and warranty? Well, the device is pretty cheap, available for under $50 at Walmart, Macys, Amazon, and other retailers.

You may think, “hey, it’s so affordable, let’s give it a shot.” But hold on, even at this price range, there are guns that outperform the FitRX/ProFit by a long shot.

So, is it worth your money? Honestly, not really.

The warranty on this device is one year, according to Tzumi.

However, the long-term reliability of the FitRX is questionable based on our experience with it. So, if you’re looking for an affordable massage gun that actually works and comes with a reliable warranty, we recommend looking elsewhere.

Tzumi FitRX Better Alternatives

Here are our top three recommended alternatives to the FitRX massage gun, each with its unique standout features that, in our opinion, make them a superior choice. What’s even better is that these alternatives come at a similar price point to the FitRX.

We have created a comparison table that highlights the key features of each massage gun, such as stall force, amplitude, percussion range, battery capacity, and more. For ease of use, we have highlighted those features that stand out (green color) as well as those which are weak points (red).

Note Renpho Active is a mini massage gun and you should keep that in mind comparing its numbers, as they are typically lower then in full-sized massagers.

So, without further ado, let’s dive into the data and discover which massage gun is the best alternative to the Tzumi FitRX.

Urikar Pro 2

Move over FitRX, there’s a new sheriff in town! The Urikar Pro 2 is the affordable massage gun that blows FitRX out of the water.

With almost double the amplitude at 12mm, this gun is a game-changer. Although the stall force definitely isn’t the strongest, it’s still better than FitRX. 

But the real killer feature is the heated massage therapy, with a ceramic head that heats up to a toasty 117°F (47°C).

And don’t forget about the 7 varied non-heated attachments, making it 8 in total! With 3 dynamic modes and 6 manual speeds, the Urikar Pro 2 is a customizable experience.

Plus, the adjustable handle can rotate 180 degrees, allowing for two opposite positions. 

And the best part? Use the code Urikar02 for a discounted price of only $62.9, making it a better value than FitRX.

Renpho Active (R3 mini)

You might as well go for a mini device that actually performs better than the ProFIT massage gun. We’re talking about the Renpho Active, formerly known as Renpho R3 Mini.

This little guy is small and lightweight, making it the perfect on-the-go option. And don’t let its size fool you – Renpho is a proven brand that knows how to make a good massage gun.

With a 9mm stroke length and 3000 rpm, this mini massage gun is a hybrid between a mini and a full-size gun, giving you the best of both worlds. And with a stall force of about 25 lbs., it’s definitely a step up from the ProFIT.

But that’s not all – the Renpho R3 also has a better battery life, with a 2500 mAh battery that lasts longer than the Tzumi’s.

It’s also much quieter, without any rattling to worry about. Plus, it’s USB-C enabled for easy charging.

The only downside is that the handle isn’t tilted like some other models, but it’s oval-shaped and comfortable to hold.

And at only $69.99, it’s a steal compared to other massage guns on the market.

So why settle for a subpar massage gun when you can have the Renpho Active?

Sportneer Elite D9

The Sportneer Elite D9 massage gun is a step up in quality, making it one of the best quality devices in the budget category.

It feels great in your hand, with a partly metal cover that makes it less plastic-ky than the FitRX. Plus, the angled handle is made of more rubber and is better to hold, with a thinner and more oval shape.

But the real selling point is its performance. With a stall force of about 30lbs, it’s much better than the FitRX and even better than the Urikar.

The Sportneer Elite D9 is also much faster, revving up to 3200rpm. And the stroke length is a third better, measuring slightly over 10mm.

The device is super quiet, compared to the FitRX, with a noise level ranging between 40dB to 60dB.

The sound is smooth, with no rattling. And with six attachments, it’s a better deal than the FitRX, even though the quality of those attachments is so-so.

As for the price, it is currently discounted by half and costs $64.99, available on sportneer.com. Don’t wait, the quality offered at this price is a steal.

Review Summary

With that, we come to the end of our FitRX massage gun review. After thoroughly testing the FitRX massager, we have to say, it’s likely the most underperforming device we’ve seen. We wouldn’t even consider it as an entry-level gun, despite some positive reviews we’ve come across.

While you’re free to buy it if you want, we highly recommend looking elsewhere. The specs have absolutely nothing to do with deep tissue therapy, so if that’s what you’re after, this won’t deliver.

Instead, we suggest checking out one of the alternatives we’ve mentioned or browsing our buying guides – especially the best budget massage gun and best under $100 massage gun.

Happy shopping and happy massaging!
