So I received that G9 clone today (which I'll call the G9c). First thing I'll mention is that interestingly, the G9c's mousefeet are actually smaller than the actual G9x. I don't have my original G9 anymore but I'm pretty sure they were the same size as the G9x, so for whatever reason they simply decided to make the feet smaller. Along the same lines, the weight tray is actually slightly different on the G9c too so they aren't interchangeable (though I'd be surprised if anyone here will be using that). Next up is that while the Precision grip fits on the G9c, for whatever reason it sits very slightly lower than it does on the G9x, which causes it to drag with the stock feet. I tried replacing them with some generic IME3.0 feet I had but it wasn't any better, so unless my unit is just out of tolerance then you'll need some slightly thicker feet if you want to use a grip.
As far as the stock DPI steps go the lowest DPI step is 800, with the next ones being 1200, 1600 and 2000 (didn't check further than that since I don't care, but there are 7 total). The taobao page does mention 200-12000 DPI so perhaps there is some software to customize the steps? Cable is not amazing, though I have become spoiled by paracords and wireless mice anyway. But luckily this thing uses the standard size connector that most mice have rather than the smaller one the G9x uses, making it easy to swap out with any cables you'd already have.
Complaints out of the way, I'll move onto what I like. First is that aside from the aforementioned dragging issue, the actual G9x precision grip fits just fine (I'd say it's more secure actually, but that could be just due to my G9x wearing with age). Mouse wheel is actually pretty decent and the middle click is way better than the actual G9x. There's a bit of pretravel on the LMB/RMB but not too bad, and the clicks are fine (some type of blue Huanos as you'll see in the pictures below). The side buttons and DPI buttons are streets ahead of the original G9x; instead of whatever the mushy buttons Logitech used, they feel and sound distinctly mechanical on the G9c.
Weight of the G9c without a shell or tray is 70g vs 78g for the G9x (95g for the G9c with the precision grip). Build quality is fine, not gonna win any awards but definitely better than some of the generic mice I've had. As for performance I haven't done any in-game testing but I don't notice anything inherent terrible just mucking about, but I've included some mousetester plots (frequency does look a bit wonky, but I'm not well versed in reading this stuff so maybe it's normal?).
