Query: Regretting this Purchase

We thought that this Bedwetting Alarm with Pad was the perfect solution for our son who just turned 7. He sometimes has accidents because he is a very sound sleeper. It didn't turn out the way we hoped. The alarm went off because he was sweating a little, not wetting his bed. I finally had to remove the pad because the alarm drove us crazy. Everytime we went up there, he was not wetting his bed. Don't waste your money on this pad, because you can't even return it.
