I have seen some keepers using those enclosures, I dont have any experience with them since I never used one but the people that does use them I havent seen them having any problems with it
My experience is that mold grows quicker in these than normal enclosures. There is no front ventilation, only top, so it stays humid a lot longer and ventilation is pretty poor.
You probably wouldn't be able to use it for arboreal T's cause of how and where they build there webs but other T's it would probably work and only other thing is lack of ventilation like Silox said.
