Works great. Used, but in good condition. Some scratches on device as shown. All parts included. This device has worked very well to train my stubborn dog. No subscription required. It is controlled with a free app on your phone. You can set up a 4-point custom fence area, or use a circle-shaped area. Very easy to set up and use. We no longer have use for it. Goes for $250+ new. Asking $150.
