We ordered 3, T10s with sliding glass doors about 5 weeks ago and they should be here any day.

I felt the 12" was too shot and the 18" too tall to heat so we went with the 15". We have a Dumerils who is gonna be a big girl one day. I figured the extra 3 inches will provide enough room to comfortably get her in and out and for an extra $45 it was better to be safe than sorry.

From what I understand they are simple to put together but require a little elbow grease and caulk. If useful I'd be glad to post any tips/pics after they arrive and are set up.
