We graduated from an Exo-Terra glass viv to an RBI PVC viv a few weeks ago and we couldn't be happier.
Our boy got the space he needed and we no longer have to mist twice a day to try to maintain humidity.
Our setup is a 2x3x12" with LED lighting and a UTH and RHP, both from RBI. We added a Herpstat 6 (for the inevitable additions) to control temps.
The fold down door works well for us. My only criticism of the RBI viv is that the finish on the cuts aren't very clean, especially the door which I lightly sanded to take off the rough edge.
