Query: Laser Button Didn't Last Long

I liked this model in every way, but it didn't last, and that's the bottom line. I decided to try a AAA battery powered model because the laser pointer I used before used expensive batteries. I loved this model, but after only a few months of use, the pointer button gave in. It ended up being as costly as the special battery using laser model I had before.
