PROBLEM: 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.

SOLUTION: positive

PROBLEM: Fast shipment and easy to install. I don’t have any mechanic experience and even have my friend install the back off camera for my car last year. My friend is out of town for his business trip and I have to install it by myself and I did it just in 30 minutes!!! It worth my dollars and quality is good over my expectation. I am still exploring all the features of this new car radio (sorry I am not a very high tech person) but so far it meets all my needs and functioned very well for me. Quick and easy to connect with my smartphone.

SOLUTION: positive
