Query: What a shame!

SO well designed but... SO poorly made! loved my first one for about a month and a half until the left mouse button started sticking. (dragging everything I passed all across my screen -- you are DEAD when your left mouse button sticks.) But I liked it so much I bought another one and now, two months later... THE LEFT MOUSE BUTTON IS NOTABLY STARTING TO STICK. So I wanted to get this slam in before I inevitably become paralyzed (AGAIN). My next stop is sadly not available on Amazon but if it works for three straight months I'm going to urge them to market here. Manufacturer is Fentek, and design seems comparable, which is hard to find. Again, this Adesso is a GREAT design -- just without a reliable left mouse button it is beyond worthless.
