No Leaks, No Snakes

In Feb of last year I bought your pet door.  I never write a review, but feel a necessity to do so now.  The down side is it was costly, and a little noisy.  The up side is it is by far the best door I have ever had.  I haven’t had one snake sense I installed it, or any issues with wind blowing it open.  My dogs run from 25 lbs to 110 lbs and have no problems negotiating it.  THANK YOU for making a quality dog door.
