Dierya Falcon: PMW3389 On A Budget

It’s really good to see the PMW3389 appearing on more and more budget mice

It’s been a while since we’ve done a mouse review on the channel, but today we break the long streak of keyboard videos! Big shoutout to Kemove for sending out a sample of their new Falcon mouse. By the time you read this, this mouse will have been released (October 2021), retailing for $49.99. I’m very interested to see what Kemove can do in the mouse space, as their 60% keyboards like the Shadow and DK61E are excellent budget offerings. Taking a peek at the Falcon’s specifications, it definitely looks promising with a PMW3389 sensor and Huano switches.

Package contents

Good news for RGB aficionados, the Falcon has plenty of that red, green and blue goodness thanks to a diffuser on the inside. There is actually a gap between the bottom and top shell, allowing for a thin strip of RGB to run around the entirety of the mouse. The only branding to be found is the Dierya logo on the inside. The RGB is configurable with the software, which can be downloaded from Kemove’s website.

Plenty of RGB

I’ve become increasingly cautious of honeycomb mice, as I have had my fair share of problems in the past, whether it be creaking, shell looseness or frame bend. With that said, the Falcon’s shell felt surprisingly robust. There is virtually no frame bend, and more importantly no shell looseness or weak areas. Some creaking here and there but nothing alarming. The Falcon does pack some extra weight at 78g, but for most users this trade-off is well worth it.

Medium-sized mouse

The Falcon’s shape is the most interesting—or polarizing—point of discussion, and it’s not a shape you see very often. Drawing inspiration from the Xtrfy M4, I’d classify this as an ergo/claw hybrid, as it features an ergonomic side design, yet doesn’t have that higher clicking point and finger grooves you’d associate with ergos. Comparing the Falcon with the M4, it does have more pronounced curves, especially on the left side. As a matter of fact the inward curve on the left feels quite aggressive, which I found surprising as this is Dierya’s first foray into the mouse market. I’d recommend this one for palm and claw grippers, while fingertip users may be better off going for a more neutral or ambidextrous design. Although it’s slightly bigger than my G Pro X Superlight, it felt very comfortable (size-wise) at a hand size of 18x9cm. This mouse will favour medium to large hand sizes, and for smaller hands (<16cm) a palm grip should be just fine. This does feel like one of those shapes that forces you to hold the mouse a certain way, and with my grip style I had some difficulty finding a consistently comfortable grip. Sometimes my right thumb was positioned further back, touching the area where the mouse starts flaring out, which obviously isn’t ideal.

Palm and claw works best

Overall the clicking experience is solid. The primary buttons felt crisp and tactile, with medium pre-travel and low post-travel. I did detect some wobble when clicking towards the tip of the buttons, but for practical purposes this is negligible. The primaries do have some side play, which wasn’t perceptible during general use. Most importantly, the tension on the buttons is good and they didn’t feel loose or flimsy. The side buttons weren’t as impressive though, and they felt quite mushy past the actuation point.

The Falcon’s default DPI levels are a bit strange, but it can easily be changed with the software. The 3389 can be pushed up to a whopping 26000DPI with increments of 100. All seven buttons are reprogrammable, and we have the usual options including macros. Then the software offers lighting control, a few mouse parameters like scrolling and double click speed, as well as polling rates of 125 to 1000Hz.

78g on my scale

Performance-wise the Falcon is rock solid with a PMW3389 sensor and Huano switches. Huanos are of course a bit heavier than Omrons, but they have really good tactility. The Falcon will work great for FPS games, but you might want to find something with lighter clicks if you play MOBAs. One of the highlights of the Falcon was the feet, and the glide was exceptionally smooth on my Ducky Bon Voyage desk mat. Just remember to peel off the protective covers when unboxing the mouse. These covers are transparent so can easily be overlooked. Unsurprisingly the 3389 sensor offered flawless tracking with super low LOD. The Falcon has a paracord style cable, and I didn’t experience any issues with cable drag, however if you’re very picky you might want to put it beyond doubt with a mouse bungee. As I alluded to earlier, the shape didn’t work that great for my fingertip/palm hybrid grip, and I wasn’t quite able to aim like I do with my Superlight, but nonetheless I pulled off a few nice shots in CSGO.

While the Falcon didn’t quite work for my grip style, I think this is an excellent first offering from Dierya. It’s really good to see the 3389 sensor appearing on more and more budget mice; no more spin outs and 4-5 DVDs LOD! There is a lot to like about the Falcon, with the standout features being the sensor, shell quality and mouse feet.
