We are really pleased with the two 20 x 10 canopies we ordered.  We aren't planning to use them until this summer, but we did open and set them up to make sure they were undamaged.  Took 10 minutes to set one up.  Just need four people, one on each corner.  I was going to rent a party tent, but these were cheaper and they don't have to tear up my lawn with stakes and ropes and they can be used again.  Very pleased!
