I think I already got this order last week.
Collars
Within a month my dog managed to shred the collar and damage the M5 unit. This was after I sewed the loose collar piece together so the collar would stay somewhat snug, as it should be.

Collar works great. Dog kept scratching cover came off that's why I gave it a 4. Hes use to it now. Not bulky working well!!
Great item!
Our dog ruined his old collar key and he was experiencing problems getting his pet door to open. We bought this new one that is better than his old one and now everyone is happy, we are hoping this one lasts a lot longer than the old one! Putting in this dog door was the very best thing we ever did and Sammy is so happy to have his own door!
great for water dogs
With a pup who I'm convinced is half dog and half fish, the MS-5 (Water Proof) key is very convenient because I no longer have to stop her every time she wants to launch herself into the pool when wearing a collar key.
