Query: Worked great for two years

I've used one of these little mice for over two years with no problems. My experience with cordless mice is the batteries go out just when you need them most, so corded is the way to go. Just recently, the latch that holds the retractable cord's door closed broke, so I just bought another Pocket Mouse Pro.The only thing I don't like about this mouse is the cord tends to have a coiled memory, that is, once it's unrolled, it tends to stay curly. This means that it often comes out of the mouse semi-coiled, and then easily gets tangled up with the mouse or curls under the mouse when you are using it.
