Bests & Worsts Reviews from Amazon

1 week in to it and it's eaten through 2 sets of batteries. This alarm is worthless! Do not buy this alarm! Really, I do think that the positive reviews are padded by the seller or manufacturer. It is NOT good construction, It is NOT loud, and the batteries do NOT last more than 2 days. --UPDATE-- So after returning the the first unit, the seller sent me the new version to try out instead. Being the sceptic that I am, I put it through its paces. It has yet to fail. The battery problems with the old unit are not present with this one and the features that made me want to buy it in the first place are still there. I don't know what they did, but whatever they did worked. I am happy with this new alarm, and with the seller as they bent over backwards to make sure the problems were fixed.
