Query: They aren't defects

I read the many reviews saying that they received a defect, but I decided to take a gamble and bought one. When I received it I was very disappointed as it didn't work. I played around with it some more and realized that I was simply using it incorrectly. It is actually kind of confusing. You have to point it at a tv and hold the mute button to program it. You have to hold the mute button for a while for it to work. It is not very responsive and you sometimes have to hold a button for it to work which is why I gave four stars rather than five. In all, it works and I like it. It's a lot fun to prank people with this and laugh at them.I would definitely recommend this to a friend.
