They were late arriving in the mail but I guess that is not the companies fault. I hope they last longer than a year for what they cost. I’m still new with the system so it took me a little to get things programmed as I have 2 different dogs and 2 different feeders. For now they seem to be working fine. I do wish they had some type of insurance on them so when one of my babies lose it in the yard it would not cost the whole price again. Just my opinion.
