I am extremely happy with my pet door and buying experience Review by Ellen D.

I bough the ThermoSash IIIe #10 last March. True to the description on the website, it was very simple to install. I could even do it myself without any help from my neighbor or a handyman. I have an 80 lb. German Shepherd Dog who is active and always on the alert for unauthorized activity in the backyard. She runs in and out all day long. The unit is just perfect. It is sturdy and holds up to regular use. The seal is very secure and did not let any of the 100+ degree Texas heat in during the Summer months. It is easy to keep clean and is not an eyesore in my bedroom where it is installed. Your order and delivery service was great too. Although the unit was on backorder when I placed my order, it was shipped out 8 days later.
I am extremely happy with my pet door and buying experience and wanted to share that with you.
