Q: I was skeptical that this would work to keep my hound dog quiet - but it works like a charm! Maybe because her nose is more sensitive?? We don't always put her bark collar on, but when we let her out at night when her barking would be more disturbing to neighbors, it works as described. Sometimes we only put the collar on and not activate it - that also works now that she associated the spray with the collar.

A: positive

Q: The tie cable to keep this on the pool is atleast 8 feet to short to reach the ratchet to tighten it. Basically worthless at this point, definitely won’t stay on for the winter.

A: negative

Q: I know it's tough, but do spend $20+ more on a better battery that will charge; hunt eBay if need be. Don't waste your time with trying to use that stupid warranty, by that time you have paid to ship it to them, most likely, and they sent it back, you won't be able to send it back to Amazon.

A:
negative
