Query: Even on sale, this is a rip-off.

This game clock (I bought two) is very user-unfriendly, but you don't have to worry about that, because they don't work for long. I bought new batteries for each after some of the digital display characters started not to show up. It wasn't the batteries, so I pressed the reset button in the back. Now barely any of the characters show up on the display, making them illegible. Now I'm the proud owner of two unusable game clocks that I tried to save money on. Oh well....made in China, I guess I deserve it.
