This is actually the second one of these I've purchased. I bought one back east to paint a car and left it with a friend there. Just bought one for my shop out here. It's surprisingly low cost and seems pretty rugged. So far have painted one vehicle in each, both came out great, no debris in the paint at all. I was going to build a single bay of my garage into a paint booth, but this provides a ton more space, proper ventilation, etc. I was able to lay out the car (small sports car), trunk, hood, doors, etc, and still have plenty of space to walk around while painting.
Two recommendations. First, I purchased an extra blower fan for a backup. If the main blower fails during a paint job, you don't want the booth collapsing on you. Second, I built a housing for all three blowers with HVAC filters in it, such that the blowers are only blowing filtered air.
Only downside is the big one is a little unwieldy to collapse and store. They should make the storage bag a tiny bit larger. I used a shop vac to try to deflate it as much as possible, still couldn't quite fit all of it into the storage bag.
All in all, love it.
