I donít know either this weight try or the mouse itself. I have Logitech G9 mouse. However the weight tray no longer seizes grasp. I can thrust it inside and it clicks except the tray simply slides out over again. I can place the mouse cover above it however it clatters while I shift the mouse and I can sense it whilst I play games. My mouse is fine out of guarantee. So is there whichever method I can obtain a new tray. I am sure that it is simply a tray for the reason that the tray does clack in and while I push it a next time it does expel not that I require to shove the button to compose it expel any longer.
