I have a dr120, a sunhut, a new hydrohut, and have had a few old hydrohuts as well. The old hydrohuts had problems. The new hydrohuts have lightweight zippers. The dr120 is little more than tinfoil sprayed with a plastic outer coating. The sunhut has heavy duty zippers, a reflective interior, and a heavyweight fabric outer layer. I would not expect my dr120 to survive many set-ups or break-downs. It got pinholes quite easily and I cannot believe they would make a tent so lightweight. Panda poly would last longer. I am waiting for my hydrohut zipper to break any day now. The sunhut has all the venting options, better zippers, and more durable construction. Out of all the tents I have used, I would only buy another sunhut.
Only difference I have dr150 and its garbage compared to my sunhut. I do think their new grolab may possibly compete now but old gear is horrible quality imo.
