Poor Quality
This dog collar worked for approximately 3 months before breaking. The build quality is poor and I do not recommend it for that reason.

It works!
The no-bark collar is effective...it's a bit cumbersome for my little dog to wear, but it is helping to teach her "no bark!"

With Modification, worked for my JRT
This product worked, with modification, for my Jack Russell terrier's barking problem. The collar was way too long, and when I trimmed it, it started to unravel. I eventually had to buy another better-fitting collar, and mount the device to it, by using a hole puncher. That worked.

It is the only thing that keeps Berry quiet. I only use it on him when I'm leaving to go to work. Without the bark collar, I would have IRATE neighbors.

I do recommend buying extra batteries, if you don't have the rechargable kind. I had to change out the batteries this morning, and was glad I had the extra ones on hand.

It's quite good, but....
This product worked great from the start on my german shepard - I wish I had purchased it sooner. However, it hasn't been effective on my australian shepard. Perhaps it's all the hair he has on his neck - I plan to clip him for the summer and hopefully it will prove effective.

Innotek Bark Collar
This collar seems to work well, comes with good documentation, but if you have a barky dog, u have to recharge it alot. The rechargeable battery feature is by far the best selling point, making it much more economical than most other brands with the disposable batteries. The dog is definitely quiter, but if the dog does go on a roll barking, he can usually defeat the collar. It's worth the money, and works most of the time...
