Genuine High Tech Power Pet Door Collar with Digital MS-5 Transmitter

I called and left a message with a concern about one of my pet collars. I got two different responses within five minutes, a voicemail as well as an email. And they had already handled the issue!

Great Products!

The High Tech Power Pet Door Collars are always great. Thanks for making such wonderful products for our fur-babies!

my new ms-5 does not work at all. i have 2 dogs , both with what i think are the newest version of the ms-5 because they have a green led not the usual red. only one will open /close the door.
