The product itself is fine except that sometimes it catches the nail. I found the service VERY unsatisfactory. It took a month to receive it. I called after two weeks and the woman who answered was very impolite. She said it will take 3 to 6 weeks for delivery. It did not say that in the ad.

Bark collar
It worked well, but I felt bad when it went off. My small dog would jump and yelp. I don't think it hurt her though.

Good product
Our small dog used to bark at the TV, doorbell, and anytime we put him out side. Less than a week later he already stopped his annoying barking and doesnt need the collar anymore. Worked great. As far as the battery goes I had no issues with it and it still works. It is not a big deal anyway, you can find the battery at any supermarket.

fast ship/worked great
The collars I orderd worked fantastic for my 2 American Foxhounds. I take them off in the evening as the probes are quite snug throughout the day. I put the collars in yhr morning when they first go out (I also have 3 other A.Foxhounds who are not as noisy), and always remind them not to bark. Some days there are no attempts to bark at all, so there is that psychological edge that they know what will happen.
Very quick shipping.Very satisfied, now my daughter wants some for her 2 yappers!

Satisfied. Its done the job!
I started using this on my roommates dog since it kind of a needy dog, and continuously barks to get what it wants. If I didn't know better I think the dog wants to train me. Upon using this neck collar, the dog has gone from a full blown bark, to a small yelp. Granted, we don't use the collar on all the time, but I have noticed a substantial decrease in the barking. There has been a slight skin irritation on the dog in the beginning, but it's pretty much non-existent now. For me this collar worked like a charm and I'm very satisfied with the results, specially for the price.
