Purchased an in ground fence system from Radiofence.com 7/2014. Three months in, collar came off my dog and was lost, so I contacted them them to purchase a replacement. The person on the phone said the model I bought had been discontinued. No compatible replacement collars available from them. When I asked how long ago they had been discontinued RadioFence rep said "about 6 weeks ago." Turns out the manufacturer discontinued the product in January of 2014, so by the time I purchased, it was already on the way out.
Had I known this was a discontinued product and not compatible with similar setups I would have stayed away, hands down. I guess keeping customers informed is not how these guys make a sale. Be warned.
