Overall a pretty good product. I would recommend it. However, the battery on the receiver does not last as long as I would've hoped. It has to be charged about every day or two. On the other hand, the charge on the remote lasts quite a while. If your dog needs a lot of supervision and training, I would recommend buying a second receiver collar to switch out with when the other one is charging. It has some really good features and both the remote and receiver seem well made. Lastly, I would recommend buying a replacement plastic collar to switch out with the regular non-plastic one that comes with it.
