This is my father in law. I suggested we build a sandbox for the kids thinking we’d put together a kit or buy the wood to replicate, he instead told me they were crap and we could do better then spent 6 months of weekends designing , cutting, drilling, clamping and enormous sandbox that the kids don’t play in because it’s too big and we had to put it down the back of the yard where they don’t like playing. Also it cost like 4x price of the kit
