The first one we received was unusable.The battery compartment could not be opened.We returned it and received another one.Had problems from the very first day.It gave shocks every time it detected urine.Thinking it might be the battery we changed the batteries out, but it started shocking even my hands with no wetness and would not turn off unless we took the battery out.So, it's useless.My daughter got multiple shocks while she was using the alarm at night and we were unaware of it for 4 nights.This is a dangerous product.Fda safety report id# (b)(4).
