This is the second product of the same brand I've bought (though I didn't know I was buying the same brand) that suddenly stopped working. The numbers don't always transfer to the screen, either skip some numbers or stop working altogether. This is very annoying. I'm going back to a brand I know and have used before. Maybe he just doesn't like my computer since he was a few years old, but it's definitely not a bluetooth issue since he has a dongle.
