I was actually looking at the Mars tents before getting the 3x3. Normally I am NOT a fan of Mars (lights and CS), but I was gonna give the tents a try.
I am a bit concerned about light leaks on the Mars 3x3, since it does have 2 "D" side doors. I won't know for sure until I set it up.
I have a badly aging
Vivosun 3x3 that will be replaced as soon as I clear a few things up (like my own health..nothing serious, just a PIA)
Since most have never heard of Unitfarm..I posted a link. They are imports and the only contact that I have ever had with them was a few yrs ago when I tested their Cree/Oshram UFO80 (got one for free, and while not a fan of Burple..this thing rocks)
NOT AFFILIATED!
