This affordable mobile gaming controller may be rough around the edges, but it’s a solid cheap alternative to the Backbone One

Two-minute review

The GTX 735 Mylox Wireless Mobile Gaming Controller is a budget-friendly alternative to some of the best mobile controllers^[2] on the market, offering iOS and Android compatibility.

Coming in at less than half the price of our current top-rated mobile gaming controller, the Backbone One 2nd Gen^[3], the GTX 735 Mylox is a great choice if you’re a more casual user or if you’re buying for a younger gamer. To keep costs low, there are some compromises: aside from its RGB lighting, the Mylox controller is a bit plain, and it isn’t the most ergonomic.

The buttons can be a little stiff, and it connects exclusively via Bluetooth rather than USB-C, so you’ll need to consider both battery life and the potential for some latency.

However, there’s a lot to like here. The grip extends and ensures your phone is pretty tightly secured in the controller, aided by the rubber base, and there’s a recess to accommodate the camera bump. While this design may not be a perfect fit for every phone, it is serviceable, at least, for a wide range of models.

GXT 735 Mylox: Price and availability

• Costs £44.99 (around $60 / AU$90)
• Only available in the UK
• Cheaper than the Backbone One

Sitting more on the affordable end of the spectrum, the GXT 735 Mylox mobile gaming controller retails for £44.99 (roughly $60 / AU$90) and is available at a number of retailers in the UK. That makes it about half the price of our current top mobile gaming controller, the Backbone One, and one of the most affordable options available.

If you want to save even more, I’ve seen it on sale for as low as £35 during the process of writing this review, and you can expect to see this price around major sales events.

GXT 735 Mylox: Specs

GXT 735 Mylox: Design and features

• Not the most comfortable
• Buttons can be a bit stiff
• Fits a range of phones

Available in black and grey, the GXT 735 Mylox mobile gaming controller is simple and understated in design. The two “arms” of the controller can be pulled apart to reveal an extending mechanism where your phone rests. It isn’t particularly sophisticated, and while its universal design will suit a wide range of the best gaming phones^[4] – and worked well with the devices I had to hand – it won’t be the perfect fit for all.

Note, though, I have found that I frequently pinch my fingers in the bed mechanism when I remove my phone.

While the GXT 735 Mylox does lack character, with the only real accents of interest being the RGB lighting behind the controls, the more basic setup is welcome for those who want to use it on the go without looking too flashy. The budget build of the model does make itself apparent, though: the buttons are all slightly stiff, lacking the smooth and spongy responsiveness that other, more premium controllers such as the Scuf Nomad or Razer^[5] Kishi Ultra offer.

In addition to the D-pad, face buttons, and two joysticks, there are four system buttons: turbo, select, start, and home. The shoulder and trigger buttons are microswitches and pretty springy, although I have some concerns about their longevity. The USB-C charge port is seated at the tip of the left side of the body, and there’s a small lip on the underside of the extendable rubberised phone bed to keep it secure during use.

The controller isn’t designed with optimal ergonomics in mind, and it could be uncomfortable for those with especially small or large hands. I found mine started to ache about an hour in, especially when playing on standard brick phones versus larger XL models.

It lacks some of the convenient design features of its pricier competitors; there’s no passthrough charging and no 3.5mm headphone jack. Still, at its price, those are pretty fair omissions. However, it’s a shame that you can’t charge and play.

GXT 735 Mylox: Performance

• Easy plug-and-play setup
• Decent compatibility with a range of games
• Responsive enough

When it comes to performance, the GTX 735 Mylox wireless mobile gaming controller offers a responsive and easy-to-use experience with some minor caveats.

Game support is wide-ranging, for controller-friendly iOS and Android games as well as cloud gaming with PC, PlayStation, and Xbox titles, although an important note is that PlayStation is supported only on iOS.

I tested the controller predominantly on iOS, playing games such as Zenless Zone Zero^[6], Katamari Demacy, and Vampire Survivors. There’s no game compatibility list that I could find, and support outside of Apple^[7] Arcade was fairly spotty. Even when it does work, there’s no guarantee that it’s seamless – Stardew Valley, for example, wasn’t very well optimized.

Connecting the controller via Bluetooth is super easy, and while I always prefer USB-C connectivity for minimal input lag, there’s a lot to be said for the universality of this controller. My phone slots easily inside, and the tray offers a recessed area to allow for the camera bump on most phones.

Its haptics are nice, but incredibly dull. I would have liked a punchier feel, even in a budget model such as this, and the RGB follows in kind with slightly washed-out colors. That being said, it’s a fun option, especially for younger players, and can easily be toggled by pressing the turbo button and clicking the right trigger.

When playing for more than an hour or two, those poor ergonomics I mentioned earlier make it quite uncomfortable – I had achy wrists and hands for the majority of my testing. I wouldn’t recommend it for regular mobile gamers, as such.

The battery life is decent, especially with that in mind. With RGB lighting turned off, it lasts roughly 12 hours, and with lighting on, it’s 5 hours.

Should I buy the GXT 735 Mylox?

Buy it if…

Don’t buy it if…

Also consider

If your budget will stretch, it’s worth considering our current top mobile gaming controller, the Backbone One; but our favorite affordable alternative is also a great choice.

How I tested the GXT 735 Mylox

• Tested for over a week
• Compared to other mobile controllers
• Tried a variety of games

I tested the GXT 735 Mylox Wireless Mobile Gaming Controller over the course of a week, playing a variety of OS games to test compatibility and user experience.

I tried a wide variety of compatible mobile games, found mostly through trial and error. This included plenty of Stardew Valley and Zenless Zone Zero, in addition to a few hours in Katamari Demacy and Vampire Survivors.

I compared the 735 Mylox’s performance to other mobile controllers, including other budget-friendly options such as the GameSir X2s Type-C.
