In general, this is not my first mouse from razers. And the same problem, clicks. The click on the wheel stopped working with not strong pressure, now it works when you make an effort. Considering that this is not my first problem with mice from a razer, I feel there will be others, such as: double click, a bug with scrolling the wheel. All problems are solved quite easily, but you have to disassemble the mouse. There was a mamba before the lanshead, it lasted 4 years, but the first problems began after 2 years of use, with the same one after 5 months. Think for yourself whether to take it or not.
