We're in the process of our build and I just installed the Pool Guard door alarms. They seem like something that should've been discontinued in the 90's. We have two separate patio doors that I need them on; of course one of them doesn't work properly. I've searched this site and see that some people remove them after inspection; we have a two year old so they will remain up. I can only find one other brand of door alarm (and they have pretty bad reviews). Is there anything out there that works, will satisfy our final inspection and most importantly help us keep our son safe?
