So far so good. Could use a trimmable spacer though.
The product works extremely well, and both pets (small spazzy puppy, old lazy cat) are adjusting to it more quickly than I expected. They both had no problems with the magnetic collar fob, which surprised me because it seems a bit large & heavy to me.
If your door panel is one thickness for the entire area you're installing, it's a total breeze to install. We have an older door though, and the lower panel ends about midway up where the pet door needs to be, so i had to custom cut a spacer to go around the top half of the hole. It's not Dog Mate's fault, but it would be nice if they included some thick foam or rubber gaskets that you can cut to fit in those circumstances.
Easy to understand instructions
Easy to install if the area for the hole is the same thickness throughout
Seems sturdy so far
ConsInstallation requires custom carpentry if the area where the hole will go has more than one thickness.
