I used X7 before, the quality of the sensors is worse, but otherwise there is no comparison. It would be better if I bought 4 of these for the money.

Pros
All sensors work perfectly, on any surface the accuracy of offsets is at a height.
Cons
The mouse is equipped with disgusting software, the purpose of which is to collect data from you and in additional useless gadgets. It is not possible to register and install a full-fledged macro, change the color of the bulbs, DPI accuracy and key remapping, and you can write a simple script - that's all.
