We read all the reviews before purchasing.  It seemed like majority of people loved it but the set up was a pain.  So we took everyone's tips when we put it together and it went up without a problem!  I also labeled each "set" (A, B...) with a permanent marker to make it even easier.  One thing to make sure you also watch is that you make sure the enclosure lines up perfectly with where the poles need to go (since the poles hook into the top of the enclosure)- so those spots need to be lined up with the frame (since this is where the bottom of the poles will go in).  We've only had it for about a month but kids love the oval!  Win-win situation so that my one daughter can do her gymnastics (she likes the length) and my other 2 kids can play their ball games in a circle!  My daughter's friend is now getting one as well!!
