The test unit came with dead batteries, but it works perfectly with good batteries. I was hoping to tweak the sensitivity a bit more, but haven't used it enough to really give it a fair rating at this point, oh, and it probably had Dollar General batteries! I'm not a fan of their batteries or their lightbulbs. Ha! Good luck, hope this helps.
