Genuine MS-5 Power Pet, Automatic Pet Door Collar by High Tech Pet Brand. Includes 2 Free Batteries

Exact product was shown . Delivered in mailbox but in safe secure packaged. Device had 2 spare batteries and collar device had a pull tab on it so battery inside was not being used until removed. Bought this product for other dogs that come visit since only one came with pet door . I’d buy from them again. Great product!

We upgraded from the original collar to this one. Had already updated the other dogs.

It's great to feel confident that our dog can get in and out when we're not home. Thus is our 4th collateral. They typically last about a year before they quit working. We don't expect them to last forever but for the cost you would expect them to last longer. Especially since our dog is a 'princess' and won't go in the rain so the collar never gets wet.

My pup had this collar on when she jumped out of my car while moving. I went back to find it in street and it still works perfectly!And my pup is okay too

This quit working after 85 days

They don’t last long. At 54 per one (i have 2dogs) it’s extremely expensive to keep purchasing replacements. Very unfortunateUpdate: this company is amazing. They refunded my money for my last purchase directly from them. I couldn’t believe it. I am revising the review to 100% satisfied. Thank you for such a quick response

The collar works perfectly with the power pet door. Just needed to add the battery!

specific for hi-tech door. last one lasted 5 years before it failed to transmit.
