Honestly for the money I expected a little better quality and the shelf is only an option which again for $135 should be INCLUDED. Light leak from the zippers is pretty bad. The only real pro I like is you get to decide where you put the exhaust holes and the pre-filter thing. Other than those only 2 things I mentioned I wouldn't waste you money. I promise you'll know exactly what I mean if you do make the mistake of buying it for $135.
SAVE YOUR MONEY! Buy a bigger tent for like $20 more and the quality would be insanely higher.
Disclaimer: I'm not even mad cause it's only my veg/ clone tent.
