text: The product works, but has a couple of quirks. When I first received it, I charged the watch about a quarter of the way, and became really frustrated with programming it. I would hit a button and the watch would just sit there for a few seconds before the selection that I made actually took place. I fully charged the it and oddly enough it seems to work ok as long as it has a good charge. I have never had an electronic component act like that before. The receivers work fair. I have had false positives and negatives. I have trail cams set up and have had animals walk by (caught on camera) where I received no alert. I have also had alerts, where if I looked at the vicinity, nothing was there and nothing was captured on camera. I also had correct alerts where an animal walked by and one of my cameras caught the animal.
