I have a few unbranded tents and they all work well for me so far. I found each one on eBay. My oldest tent is one of my 4x4s at just over 2 years I think, no rips or leaks and I only paid $45 for it. My 2x2x4 was shortly after and was only $35 roughly and the only issue is the reflective part right by the bottom of the zipper between the door flaps. My other 4x4 is maybe just over 1.5 years old and paid about the same, $45. It's damn near impossible to find a 4x4 for that cheap any more. And my newest is about 10-12 months old, paid about $205 for an 8x8. No complaints on any of them. Little or no light leaks from what I see. The big one has a velcro flap on the bottom for the intake air that my dogs got to and messed up so the light leaks in a little because I haven't fixed it yet. It's my flower tent but it's been that way for a couple months now I think and it hasn't affected anything yet so I've left it and so have the dogs. Like a few others said though, it really depends on what you want to spend.
