Picked this Climbing Dome up as a surprise for my two kids and couldn't be happier with the end result. The dome is incredibly sturdy - no concerns around multiple kids playing on it at the same time. Setup wasn't hard, but a little tedious, as the dome is shipped as a whole bunch of individual bars. The instruction manual made sense, but BE SURE TO READ THE WHOLE MANUAL before you begin - we got caught once or twice and had to back track, but overall, two of us got it built in a little over an hour. Lastly, you will want a 1/2" ratchet with an extender for the plastic caps that go on at the end.

If I had one complaint, it's that every bar is individually wrapped in a plastic sleeve, which felt rather wasteful. 

Overall, this is a fantastic product. My kids (and a couple of neighbourhood dads) haven't left it alone since we built it three days ago!
