I have 2 S8 AC Infinity (exhaust/intake). I use the carbon filter and 2 noise reduction things and a the damper. All of this in a 4x8 AC Infinity tent. Only my lights are a non-AC item.
The tent has never had any issues,
@DrDukePHD had decent holes but I got lucky I guess. Zippers were a nonissue but they have weakened over time. No discoloring of reflective, no new holes, and zippers let a bit of light out but it's not enough to really bother with. The intakes have been great, only negative would be not having independent control of the fans with the 67 controller, even that is easily taken care of as soon as I use a screen on the intake. I had a unit get busted and I was sent a replacement within 3-4 days I want to say 3. So, customer service was no problem also.
Edit: I have never owned another tent or AC component to compare brands, FYI.
