Poorly Made

i Love the electronic door for our dogs, it frees us from having to let them out and in. Unfortunately, the collars that allow them to go in and out the electronic door are poorly made and I don't know how many I've had to buy in the 5 years we've had this door. I feel we're held hostage by this company and their poor quality electronic door collars. The biggest problem is that this company doesn't have enough competition.

Not good Quality

No issues with the unit itself, but the collar is awful. Ive been using this for 2 months and the collar is already frayed and falling apart.

Don't bother with the collar...

Purchased this collar for the large slider for our second dog (puppy) only because the picture shows the MS-5 but the description says it comes with the MS-4. It has been less than a month the collar literally disintegrated, the chip only works sometimes...it is just so cheap!! MS-5 works much more consistently. For such an expensive dog door these collars/chips are ridiculously priced, extremely low tech, and unless you remove the device from the cheap strap and zip tie it to a real dog collar you will loose it...I am back ordering the MS-5 because it has already fallen off of in the yard somewhere...I think my teenage son could put together a better system with a RFID card and a 3d printer....they need an upgrade to make this worth the price!

Great human deterrent

We bought the system to keep our dog from going down the hall. We bought the second collar for our foster dog. After first day they no longer go down the hall.

My Honey has kidney problems, and the auto door and collar is a must!

MS4 collar

I've ordered 5 of these since December 2020. Two have failed, one since my most recent January order. No response from my first comment.. SECOND TIME asking, why a 600.00 door with cheap tags. ? How can this be resolved? Do I just keep ordering these tags that fail in less than a month?

Easy fix for longevity of collar

The collars are rather flimsy, before putting on my dog I cure that problem by wrapping a band of electrical tape on both sides of strap attachment get easily a year out of them.

Stop working

Test light shows battery is good, but it dosent open the door. Quit working after a few months and multiple battery changes.

Long lasting product

I have had the door and these collars for over 10 years. The system works great. Yes, batteries lose their power and yes we have had two cases where I found the top in the yard. Simply snapped it back on with a new battery and off it goes. In 10 years I have only had two collars. We notice the battery is done when our dog sits by the door and whines. it takes about two minutes to fix the problem. The door itself has worked flawlessly all this time. I highly recommend it and if it ever does stop working I will replace it with the same door from the same company.

terrible waste of money

I so wish I didn’t fork out so much money on these. The collars break constantly
