Review on TUFF Collar Dog Fence Receiver: Durable Replacement Strap for Maximum Performance by Cindy Plant

I bought two of these to replace the collars that came with the wireless fence system. Apart from the red color, the two collars I received were nothing like the standard collars. They are only about 1/2 inch wide and have very thin nylon straps, anything but "heavy duty". The collars were wide enough to fit holes for the receiver. I'll discuss this with Revain. Even if it's not a lot of money, I hate being taken. All I can say is that the buyer should be careful when dealing with this company and their products.
