100%. I haven't field tested it yet, only just received it but the material is as described, waterproof and the corners reinforced. the supports in the corners have a nylon pocket with what I presume is a metal rod in there, I don't know how strong it is for packing sake, squashing it, but it seems really strong. so far, having just shot it open in the living room (my dog huffed, attention wasn't on him), but I gathered the corners and stuffed it back into the supplied bag with the supports bunched together, it's hopefully squash smaller that way. it came folded I think, I didn't look too much into that so if one receives it, just stuff it your own way, do what works for you. The linelocs seem really genuine, I think dutchware gear introduced them as almost standard ultralight tensioning hardware, knots being ultimately lightweight of course but these are far more appropriate than any other option, being designed to be adjusted from within the tent. the cord seems lightweight
The material is good and seems to be easy to use!
