## Customer Reviews

### ⭐⭐⭐⭐⭐ Fit our 3 panel slider perfectly
*by J***N on May 8, 2024*

We have 3 dachshunds who are very low to the ground. I read review after review trying to find the right patio door insert to for our Florida home. This insert was super easy to install but there are a few caveats.1. This insert does not lock and is not compatible with your current locking mechanism. (They call this out but I just want to reiterate that).2. Brushed aluminum finish looks great and easy to paint, glass is of good quality with slight tint and matches the tint on our existing sliders.3. Magnet is very strong on the dog door. You may need to remove the bottom magnet at first until your dogs get used to it.4. Customer service - they answer their phone and are happy to help you.Overall - this unit cost more, but the quality justifies it. If you are looking for a short term solution, this is probably a bit overpriced. but if you are looking for something you could use for years to come...this is the one.

### ⭐⭐⭐⭐ Good winter dog door.
*by H***L on February 6, 2025*

Overall, the door works very well. We have had several dog doors in this location over the years and bought this one because it was supposed to be more resistant to cold air infiltration. The previous doors we had tended to blow open in bad weather and then not seal shut again, which led to to massive cold air infiltration, and unhappy houseplants. This door works much better. It seals shut and stays put in the cold winter wind. There is also no collection of dog hair (huskies, in our case) on the magnetic strips, so the magnets lock it down solidly. We had to clean the magnetic strips on other doors about once a month, but this door does not have that issue.We had our door installed for three weeks and were happy with it, until one of the corners of the top hinge came loose and the whole door sagged down on one side and was unusable. We contacted customer support which was very pleasant and personable, and were told a new door flap and hardware would be sent. Three weeks later (with the door closed off with the plastic panel and not available for use), the replacement door flap had not arrived. Another call to customer service -still pleasant and helpful- led to another promise of a new door flap and hardware. The new parts eventually arrived, and the we were able to replace the flap with a new one (must be handy with tools to do that). The new flap has seen several weeks of service and works well. We have had very cold windy weather and the flap stays shut. If it did not, it would not be usable in our location.So, a good door, overall. The seal around the edges of the whole panel works well, but the glass portion is nowhere near as cold-resistant as our sliding glass door glass, which does not frost up in the cold (10f and below) like the dog door glass panel does. I don't think there is any better dog door panel out there, however, so that's just how it is.One of our dogs took all of three seconds to figure out the thermo dog door, and the other, smaller one, took a couple of days, but both use it all the time, now, with no problems. We use it to give our dogs access to the house and outside while we are not at home, and block it off at night with the lock-panel, which works great to keep unwelcome wildlife out.Our dogs are in the 35-45lb range and have no problem with this door. A small dog would have to hit it pretty hard to get through, which would depend on the dog's personality. We have the large size and presumably the smaller sizes would be lighter and easier for a small dog to use. Our advice is to not go any bigger than you need to, because the door flap is much heavier than a simple flexible plastic panel, and a large panel is heavier than a small panel.If not for the mechanical failure and slow replacement, I would have only positive things to say about this dog door, because we like it just fine. It is expensive, but it is also a much better door than cheaper alternatives.

### ⭐⭐⭐⭐⭐ Improvement over my previous doggy door.
*by S***B on April 23, 2024*

Looks great, installs easy, heavy duty and muched improved over the previous doggy door that I had in our patio. Even on windy days you don't feel a breeze coming through the flap. In the mornings, when it's cold outside the pet door doesn't feel any colder than our patio door next to it.
