Try the Tri-tronics. I never had one stop working before the collar just plain wore out. The sensor was in the collar so you would have to replace or send it back. But never a big deal. A couple of bucks and a couple of days.
I have the tritronics bark limiter on my chocolate lab. Sure is quiet since I put that on him.
I tried getting him with the regular e collar, but if you miss it defeats the purpose of the exercise. This unit gets him every time. It only takes a couple catches and even he "gets it". 'don't bark in the kennel"
