I havent owned any other tents, so I dont have much to compare it to. I have 2
vivosun 3x3x6 tents. Made about a year apart. They are both working out great. I prefer the older one, due to a couple little things that have nothing to do with the tent as a growing environment. The new
vivosun velcro strap that holds the door open is 1/2 the length of the original one, so you have to open your front flap all the way to be able to use the velcro to hold it open, not a big deal. And the 2nd one is the top zipper stops at the front of the tent. Just enough to open the door flap. The old one zipped all the way around the tent, so you could zip the tent fully open made it easier for defoliating.. but these arent deal breakers for me.
All in all, I'm very happy with
vivosun tents. But as I said I have little to compare it to. My buddies tent is some other brand name, he paid more and it's not as nice, so I guess that's good
