A fantastic (if pricey) mouse plagued by unreliable switches
Reviewed in Canada on October 2, 2019
I ordered this mouse instead of the G Pro Wireless because I have a g502 Proteus which has lasted me years without issue and been the most comfortable mouse I've owned since my old mx518.
The Lightspeed version feels slightly lighter than the wired version and the scroll wheel has less heft, but otherwise it feels identical and the lightspeed low latency tech Logitech is using is really incredible. Macro support is great, and although the G hub software is still less user friendly than the old Logi Gaming Software, I was very impressed with the new mouse and ready to replace my wired g502. So... why two stars?
Within a couple days of owning it, maybe 5 hours of usage total, I noticed that the left button would sometimes double click when I pressed it once. It's now doing this for ~50% of the presses and it makes the mouse utterly unusable. I've tried turning it on and off, running it in wired mode, resetting the profiles and reinstalling the software and nothing has worked so far. I reached out to Logitech support for an RMA and they haven't replied yet. If I get a working replacement I'll update this review, but now I'm worried about reliability with this mouse in a way that I've never been about a Logitech product before. There are multiple complaints about this same issue elsewhere so I can't recommend this mouse for now. I was so ready to go wireless too...
Received an RMA replacement from Logitech after a lengthy and convoluted process where I had to send a video of the mouse double clicking so that they would send me a replacement without shipping back the broken one. The replacement mouse was great for about 3 months, but now the right mouse button registration "flickers" on and off when it's held down. This is obviously terrible for any FPS where you need to hold to ADS and I've had to switch back to my old Proteus again.
Now I have two useless $200 wireless mice and after requesting another RMA, they now want me to record myself destroying the replacement with a power tool before they'll send me another one. At this point, I'd really just like a refund. I really wish I could recommend this product, but until Logitech gets a new switch supplier I do not recommend ever buying one of their new gaming mice.
