Title: Unreliable
Review: I bought four of these. At first they worked well, but after a month I started seeing problems. One just stopped working entirely. I contacted customer support. They promised to send a replacement but never did. With another one, it will set/unset 50% of the time. The rest of the time it just doesn't respond to the remote and I have to reset it by removing the batteries for 30 seconds. After that it works for a while, then has the same problem all over again. This morning, another of the alarms decided to set itself all on its own! I couldn't find the clicker, so I was deafened for a while before I relocated it to the basement. And about a month ago, one of them went off in the middle of the night. Of course, we thought we had an intruder, but no, it was just the MA-S01 alarm malfunctioning. Only one out of the four has worked without incident.
