Not a bad enclosure, however, Ortur could have made it a little more rigid. That does not make a deal breaker. It does the job very well for what it was made for. They mentioned it uses fireproof fabric material - I saw their test video where they burned fire inside for a full half hour without the box burning through, though I'm not brave enough to try that myself, haha! The exhaust fan does a good job of venting out smoke and fumes. All said it was worth the $160.00 price.
