it shouldnt be clicking random if its the sensor, I would say it may be a conflict or driver problem etc. did you try updating the firmware or reinstalling windows.
If it was just jerky etc. I would say yes but if its randomly clicking that dosent sound like a sensor problem. I have torn apart a few deathadders and made some frankenstein monsters that still work today. the one I bought retail is still working for me after 2 years..
Also dont smash it against concret give it to me and I will strip it an di think i have the parts to make another one depending on whats wrong, I really need a good microswitch from on of the clickers so think about it.
