TL;DR - overall great mouse in my opinion, though the scroll wheels and build quality could be better. I wanted the capabilities of the Logitech MX Master 3 I use at work without the bloatware/cloud/spyware BS required for their new models, a way better polling rate for gaming, and a bit less weight; this fit the bill and I've grown to love it. I use it at home for remote work and gaming. A lot of stuff that could be considered good or bad based on your preferences.
Main points I can attest to for the 8K model of this mouse...
THE GOOD:
- Tweakable polling rate and DPI at a good range (with hardware buttons to boot!)
- Smooth movement, tracks great as far as I can tell
- Side scroll wheel
- Unlockable main scroll wheel
- "clicky"/"snappy" action on the scroll wheels + ridged textures for grip
- Clean, no-frills appearance (rare these days; love to see it)
- Near-silent key presses
-Included braided USB-C to C cable is excellent and not stiff unlike others (ie Corsair). Including a compact A-C adapter is also a very welcome bonus
- 3 connection modes, pairs with up to 3 Bluetooth devices
- Compatible with basically anything that takes mouse input
PREFERENCE-BASED/"OK" STUFF:
- Soft touch material, not the greatest grip (may feel "cheap" to some, though I've grown to like it)
- Matte finish, not the worst fingerprint magnet but you'll probably see oils/sweat
- Very lightweight
- Main 2 buttons feel a little "mushy" but still nice and responsive
- Battery lasts around a couple weeks @ 1000Hz polling rate on 2.4G connection
- 1-2 hours for a full charge via USB A-C adapter included using PC USB power; I just let it charge overnight after power flashes red
- Ergonomics fit my medium size hand fine, though it's nothing special
THE BAD:
- Side scroll wheel feels very stiff compared to the rest of the parts
- Scroll wheel unlock is a physical switch that requires a lot of force to press; definitely has me missing the magnetic scroll wheel from the MX Master
Minor nitpicks... I wish there was a mini guide printed on the bottom to tell you what the polling rate lights indicate. The scroll wheel also rattles a little bit when the mouse is slid sharply or shaken, though it doesn't happen much in typical use.
Last thoughts... I haven't tried to use the customization software yet (and probably should), but I'm glad it exists and is optional. Can't speak for how good it is or what customization options there are. Coming from typical gaming mice, the light weight, soft material, and "mushy" silent buttons took some getting used to, but mushiness is the price for silence, it all works, and it feels satisfying enough to me. Overall, I think it has a lot to offer at this price point and is a good deal even at sticker ($70), especially considering that Logitech sells theirs at $120 and requires an account + bloatware to customize anything now. If you can get this on sale, I think it's an even better deal.
