I have owned the climbing dome since 2017 and it is still very sturdy and my two boys really enjoy it (6 & 10 years). I reached out to Lifetime recently as some of the hardware (bolts, washers, etc.) were corroded, or in the process of rusting and deteriorating.  Customer Support swiftly resolved that issue by sending a full set of hardware.  I would recommend applying an anticorrosive on the hardware prior to assembling to avoid having to struggle to remove them later, especially if you move as often as my family does.
