My bro had this in college. He only grew one plant and than tossed it. If you got the right shit to go with it I think it would do well. Too strong a fan makes the sides suck in alot.

home box or hydro hut are a much better quality tent

I'm not really concerned with the best quality as i'm only useing to veg for 2-3 weeks. then it will be folded up and stored for 2 months till i veg again. Thats why i like it its cheap like me

It's a handy item to have. A few PVC 'T's and a couple lengths of pipe across the centers of the support frame will prevent your exhaust fan from collapsing or deflating the unit.
If it's cheap, why not?!
You will need to factor in other costs such as the lighting and ventilation systems assuming you do not have any lying about.
