Hi - I registered here because I LOVE this mouse, and I HATE this mouse.
I love it because it's the perfect mouse for my super weird claw grip, I love the weight, and I love how it works (WHEN it's working).
I hate this thing because it randomly (every 30 seconds or so) lags at tracking my movements, and every few minutes it STOPS tracking completely; I move the mouse, but the pointer remains completely stuck in place. When this happens, I can still click the buttons - for example, right-clicking brings up the menu, etc - but the pointer will NOT move until I lift the mouse then put it back down. Until I pick it up, it will remain stuck regardless of the wild movements I make.
EDIT: This issue persists whether I use the mouse wirelessly or wired. I have not tried BT, but that won't solve anything anyway.
I have tried this on 3 Harpoon Wireless mice, with old firmwares, with latest firmwares, with wire, with dongle, with polling rate at 1000, 500, 125, etc. I have changed the DPI settings, I've changed the lighting settings, I've turned off the lighting settings, I've turned off the sleep settings.
I've even disabled the "Allow computer to put this device to sleep" setting in Device Manager for EVERY USB device and hub I could find.
I've uninstalled iCUE, I've reinstalled iCUE, I've tried older version of iCUE.
The result is always the same.
Then when I grab my Razer Mamba from my other computer and plug it in to the SAME USB port as the Harpoon was using, everything works flawlessly.
When I plug the Harpoon in to other computers, regardless of USB port or revision (USB 2.0 or 3.0) it always does the same weird tracking drop outs and lags.
Guys, if anyone out there has some kind of solution or has experienced the same issues, please speak up because this thingy is driving me nuts but I don't want to give it up.
Thanks for reading this far!
