I recently had my 3dConnexion CadMouse left mouse button (LMB) not working reliably (sometimes no-click, sometimes double-click). I purchased it from an eBay reseller brand new but 3dConnexion voided the warranty since eBay is not an authorized reseller. The mouse lasted 7 months.

So I am in the market for a new mouse. I am leaning towards the Logitech MX Master wireless mouse. Does anyone have a recommendation or had any issues with the MX Master?
