Title: Piece of junk
Review: I read a previous review that this thing was a piece of junk but ignored it anyway. Well, I should have listened. I own a business and needed a "fitting room" type sensor to alert me when customers came through the door. I thought that this device was doing the job although it was annoyingly loud even at its lowest setting. However, it stopped working after 2 weeks. I returned it and although was kinda PO'd that I had to pay to ship it back, I was hopeful that the thing was just a lemon and the next one I would get one would work. I was wrong. The second one stopped working, too!
Is this product review negative?
