I have two collars and one remote so that I can work two dogs simultaneously. Durable and great range.

The new colors I purchased came quick and at a good price.

Second DT System purchased for our hunting dogs!

Been using this unit for about a month now. Really like the freedom this hands free model provides. It allows me to restrain my young energetic lab puppy to teach steadiness without fumbling for the handset after the dummy is thrown. Allows me to train solo, when a helper is not available. Only downside so far is the contact points for the battery in the handset are too loose. Had to adjust twice now because the battery was not making full contact and working properly. Collar charges very quickly and holds a charge for a long time..

I have a very well trained puppy, but he is a very stubborn breed of dog. There are times when he just doesn't want to listen, but with this collar it has really taken his training over the top. He also listens better when the collar isn't even on.

The design would have worked well, and the electronics seemed sound, however it is so cheaply made I was even afraid to use it more than one time. Switching between dogs with it's Tinkertoy kind of knob, just doesn't cut it. I returned it.

I had bought the R.A.P.T.1400 on the strength of one of their first offerings. That collar is over 10 years old, and still works great. I had some problems with the R.A.P.T 1400 collar, but the service from D.T. Systems was outstanding, I will say. My advice would be not to place the excess collar in a loop away from the neck of the dog as shown in the photos of the unit. Rather, duct tape the excess collar length down each time against the regular part of the collar, after making sure to strap the unit down tightly on the narrowest part of the dogs head to make sure that the collar will not come off. You can cut off the excess, but that will shorten the distance of the radio control.

The product was easy to program and works excellent.

I got this to replace a tri tronics it does not hold a battery long and it not as strong but I needed something that had lower settings it's doing great for that

Cheaply made, don't like 9v battery rather prefer rechargeable transmitter, don't like the on/ off system, do like the concept...
