This is a VERY well built, well working and rugged unit, both the transmitter and collar. The range is fantastic. The light function is new to me. My cheap old collars didn't have it. It sure helps see the dogs at night. The 128-step sensitivity is nice because you can set the level at the threshold the dog notices it, but if necessary, you can raise it for a correction. The batteries are pretty long lasting. The charger also comes with an adapter to charger them both at once.
