Some quotes from the item reviews on Amazon:
"Not fully insulated against light ingress / egress caused by 2 or 3 spots of poor sewing."
"You have to give it some thought to get the plastic protectors positioned correctly on the frame so as not to tear the fabric."
"Zip broke 2 weeks in"
"Zip dodgy and hard to close at the front."
An enclosure needs to be 100% secure against escape, and be so for years on end. This doesn't sound like it would be.
Other things to think about are how to heat (secure attachment points for overhead heating; how to isolate heat sources from the snake), cleanability (is dried urate removable from the surface? I don't know), whether ventilation is sufficient and adjustable enough, how to attach branches and other decor securely.
I would not be comfortable thinking that a large active snake couldn't compromise the structure of that unit given enough time by pushing small holes and going between the frame tubes and the tent wall.
