text: This tent leaks light from the zippers, as well as various pinholes all over the door. All the zippers came broken, but luckily i was able to fix them. The zippers now work alright but they snag a lot compared to my vivosun tent. The holes for the vents and ducting also leak a little light. The frame is sturdy, but bends inward a bit where the pieces of metal snap together. The extra light bar/carbon filter bar was really handy. The walls/mylar are also not very thick in comparison to the vivosun tent. Overall the tent is working well with a viparspectra 450w light in it. You get what you pay for. 3 stars due to the zippers and light leak.
