I bought the Climbing Dome for my grandchildren in the UK and after I assembled it I noticed one of the climbing handles had arrived broken. I contacted Lifetime and they are sending a replacement part from the US. Thank you to Adam in Customer Service who dealt with my issue promptly and efficiently. As for the Dome, I used the video and instructions together to build it, it takes longer than an hour to build and make sure you don't get the bars mixed up (I learnt the hard way with 3 of them!) It is very sturdy and the children (7 & 5yrs) love it! I would definitely buy Lifetime again :)
