Laser pointers

Today we bought our third laser pointer for Milo. I'm not sure what it is about laser pointers, but they always seem to die. I don't know if its because the ones we have been buying are made for pets therefore they are made cheaper or if we just use them so much they wear out. Either way this is getting ridiculous. Milo loves them though. They are a great toy to give him some exercise. He will do laps around our living room just to catch that dot. So we will see how long this pointer lasts. Hopefully longer than the last one.
