High Tech Pet Products MS-4 Water Resistant Microsonic Collar for HTP Power Pet Doors

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?

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.

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

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.

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

How can the electronic door be so outstanding, and yet the collars that come with it I made so poorly? I have 3 dogs so I purchased 2 extra collars. It’s been three or four days since we’ve put the collars on them, and the cover fell off one already, and the collar is fraying and junk. Ridiculous! I’m really upset because I purchased them for safety reasons and the electronic door was so highly rated, so I didn’t think to look at the previous collar reviews. Sound like I will writing a letter to the company who makes this door/collars- ugh!

My pups and I enjoyed them having the freedom to come in and out of our home when they wish with the collar and door. The collar worked amazingly for a week until my dog scratched on it and it came apart. It took one week for the collar sensor to break. It is not great for long term use. You'll have to keep buying these 40 dollar collars every other month

We have now purchased a total of 8 of these collars in the last 5 months and they barely last 2-3 months. Not Chewy's fault. The company that makes them clearly makes a subpar product. The electronic pet door that the collars go to works great, however, the collars are the problem.

After less then a month of use it the cover fell off and exposed the microchip. It stopped working. It may have been bumped but given that it’s meant to be worn by a dog who isn’t going to be careful it should be of sturdier quality.

This is my second MS-4 collar in 2 months .. they continue to stop working. It's absolutely ridiculous that this is the collar the door comes with, when there is a newer (and in my experience better) version available.
