Great Fit

I've tried a couple different martingale collars for my fearful GSD so she can't back out of her collar and get loose but others seemed to stretch out and become bulky or ill-fitted. This one is just right. It's cute and seems to be comfortable for her as it doesn't migrate a lot and it holds her GPS securely. The one thing I dislike is the ring for the tags. It's design leaves a pointy end so the times I've held her collar, the ring pokes my hand - ouch! I've had to change the ring. Other than that, the collars mechanism keeps my dog safe and I trust it's durable enough to last.

Chain reaction collar

We have a border collie puppy. He was pulling terribly with his harness and leash. This collar corrected his behavior

Love this Collar

We really love this collar. We like that it hangs on her neck more like a necklace not tight like a collar. We like that her tags hang on the side of the collar and not on he bottom so that you can see them. We like the rubber silencer on there too. It is reflective so perfect at night. We have had it for awhile now and it still looks brand new. We also like that it stops her from pulling when we walk her and does seem to silence her more when she barks too much.

Great collar

We really like the collar specifically because and has the attributes of a prong collar without the prongs. It is lightweight, slightly reflective, and easy to adjust. I would have given five stars but a caller is not as easy to take on and off. May be user error. Would highly recommend this collar for anyone looking for a correction collar.
