I was really happy with how this little thing cleaned my keyboard but after taking the bottom off to clean I can't put it back together. There's only one way it fits, and I really tried to keep it in place, but the side opposite the "Press" button won't stay on. It was easy to disassemble so I don't understand why it doesn't snap into place. I had to glue one side of the bottom piece to the top piece. Does anyone else have this problem? I guess I'll leave it as is with this "fix" tape, but it's disappointing.
