Kensington Ci75m Wireless Notebook Mouse (black)

Summary: It's an awesome mouse until the magnets fall off. I'm not sure if that's just bad luck or common, but I'm looking for a replacement now. Without the magnets the top half of the mouse falls off almost whenever you move it, although the mouse still works.

Summary: I bought three of these mices at different times, my first one had this issue of having the rubber on the mousewheel and the grip melt on me, as in the rubber on the mousewheel start to tear apart while the rubber where my thumb is deformed and smeared out, which created in very uncomfortable gripping scrolling and holding

The other issue, the click mechanism which consists of a deformable plastic is very easy to break since it hooks into a little slot on the frame, if the plastic end gets broken, the plastic has trouble returning to its original position making clicking impossible or very difficult.

The USB sensor is horrendous, the shiny head encasing the circuit part of the sensor actually breaks off the actual mouse itself leaving you with a stick and a circuit board on the end that you cant stick anything into, could be fixed with superglue but its a hassle and you risk breaking the circuit

magnets on both the body and the housing hold the mouse in one piece, sounds like a good idea until the magnets (which is at 3 holes in the housing and 3 corresponding holes in the body) from the body becomes detached and ends up sticking onto the housing magnets, what the means is when you pick up the mouse, your housing detaches from the body very easily

lastly, the range sucks, it wont work more than 3 feet away and it works on very few surfaces

Both mices have suffered these problems and i bought them about 8 months apart, thinking they were mainly due to just a isolated product incident. My third and last mice just ended up dying for no apparent reason after developing the melty rubber and usb problems
