I have four collars and a reciver, from wildlife materials, bought Three years ago. Dogs are now gone; since I had to move selling all in a bundle: for 900 or best offer. They have been used, they are all 1200 hour collars, used for only 100 hours or less. One was just refurbished and has not been used since. I paid 1000 for them all have lifetime warenties on them.
