Pros: price, mouse shape design, scroll wheel,
Cons: dust magnet, need firmware update to work,
This mouse feels very nice. It is a claw grip mouse, but if you have small hand you can also palm grip it. I would absolutely recommend this to small hand plam gripper and any size hand claw gripper. As for tracking, I am no expert in mouse, but it is smooth and I land my shots so w.e. The dpi setting are 800, 1800, 3500. I wish they allow you set custom dpi. You can turn prediction off. Looks sexy. The scroll was hard when I bought it but now it feels just right. The two thumb button are exactly where they should be, right above the thumb. As for complaint see other note.
The stock firmware this mouse is ship with sucks (Rev 28). It is very twitchy. You have to update the firmware.
Now there are 3 you can update to 30a, 31, 32. Firmware 31 have a ridiculously low lod unusable in gaming. 32 is ok ONLY if the surface is 100% flat. The slightest bump or uneven cause the mouse to stop tracking or jump. 30a have high lod, but that is ok, you just need to place 1 layer of clear tape over the sensor to bring it down.
