All of my current tents are AC Infinity. I have a 2x5 (prop and cloning) 2 5x5's (one veg, one flower) and 1 10x10 (flower) and I LOVE THEM. They seem to be 2x as thick as say a Vivosun tent, double stitched, smooth metal zipper (havent gotten a zipper stuck in 6 months of owning on any of them) and the interior bars just seem superior quality
