KLIM Aim review: A $20 gaming mouse shouldn't be this good

Windows Central Recommended Award

PC gaming can be an expensive hobby, and there's certainly no shortage of companies making great hardware. A good mouse is essential, though, as one of the two main input devices, whatever your budget you'll want to get a quality product that's both comfortable and a good performer.

The KLIM Aim costs just $20 while packing in features that would often be overlooked in a budget mouse. It's really hard to fault, especially at this price.

What you'll like about the KLIM Aim


It's impossible not to address the price first since honestly, it's the thing that's likely to catch the initial eye. At just $20, this isn't just affordable for a gaming mouse, it's an affordable mouse, period.

Perhaps better still is that it's not short on features despite a super-low price. You have programmable buttons on the left-hand side, a DPI switcher on the top and an optical sensor supporting DPI between 500 and 7,000. That's a bigger range than a fair number of budget gaming mice.

The sensor is accurate and responsive, boasting a 2ms response time, and paired with both my Razer Goliathus and KLIM's own RGB mousepad, it feels excellent. It feels sharp as a tack both when gaming and when doing normal PC tasks.

It performs outstandingly well for a mouse that costs twice as much, let alone for $20.

Even though it only has buttons on the left-hand side, the KLIM Aim is fully ambidextrous. I have to say that was one of the biggest surprises upon taking it out of the box, because finding a good gaming mouse for left-handers can be hard enough. But when you get it on something this good and this affordable, it's exceptional.

The shape of the Aim is great, it's a really comfortable mouse to use, and I've had no problem using it as a daily driver. It's not quite as ergonomic as my usual mouse, the Razer Deathadder Elite, but it's pretty close.

The Aim is also a good looking mouse. It comes in a matte gray finish, broken by black grips (which are plastic rather than rubber) and the RGB lighting zones. There's quite a lot of lighting on this mouse, but even then, it doesn't feel too over the top.

The companion application allows you to customize the lighting effects, along with performance features like custom DPI settings. The icing on the cake is a high quality braided cable, that while not detachable, is certainly long enough for most gaming setups.

What you'll dislike about the KLIM Aim


It's good that the Aim has a companion application, because gamers will always demand extra control over their hardware. But it's also very much like an application that comes with a low cost piece of hardware. It looks dated and it's not the most intuitive thing to use. It's hardly a deal breaker, but it might cause a little frustration if you like to constantly tinker.

There are also a couple of small things that might put some off using the Aim. It's extremely well designed and very comfortable to use, but folks with larger hands may struggle. Perhaps a byproduct of being ambidextrous, the Aim is fairly narrow, and with large hands you may find a trailing pinky or that the mouse disappears into your palm a little.

It's also quite heavy compared to some mice. It's hardly a brick, but I noticed immediately a difference to my own regular mouse, and it took a little getting used to. If you're the sort of person who lifts the mouse a lot, it may become fatiguing over time.

Should you buy the KLIM Aim?

There's really no reason not to seriously consider this mouse if you're looking for a high-quality product on a tight budget. Especially if you're left-handed.

Sure, it's a tad heavy, but the build quality is excellent and it performs outstandingly well for a mouse that costs twice as much, let alone for $20.

None of the negative points should really be absolute deal breakers, and the included 5-year warranty as on all KLIMs products should also help tip the balance.
