You won't find better for this price. I've had no luck with mine. It turns out that the wheel cannot be cleaned and cannot be repaired. Passed may change. Has pros: Very comfortable. The coverage is just great. The ability to change dpi for those who work in different programs is very useful. Not a high price. Different cons: The double click button is too far away even for a medium sized hand, but you can get used to it. After two months, the robotic wheel began to fail, does not obey, lives its own life.
