I just got there T11 2 weeks ago and it is an awesome cage.
There customer service is great.
Compared to other cages there price is good. They cut holes for lights, engrave names on cages etc at little or no charge.
I got the T11 w/ belly heat and two 8.5 cut outs on the top.
I have found in a cage that big and with it being right by my ac vent that I need the overhead lights on to keep it as warm as my bp likes it. And they still hold humidity great.
i highly recommend them.
