So, I bought the mice after I was fascinated by how light it is but I still managed to have good "control" in games. After only 4 days of use, it starts making weird noises when I use the left and right mice button. Like a "squeak" like sound. I've never inflicted damage to the mice nor did I let it fall to the ground. No one else touched that mice. I can still use the button and they function perfectly but am I allowed to claim warranty? It's annoying and it feels very weird every time I use the button. I didnt know where to upload that sound so I hope its not against the rules to post a link by "SoundCloud": Link: https://soundcloud.com/user-610858271/mouse-noises/s-m0x8y !!!WARNING!!! The sound is very loud. Lower the volume!!!
