### ⭐⭐⭐⭐⭐ Love these!!!
*by D***D on June 20, 2025*

It’s funny when people say these are flimsy. Sure, PVC pipe or wood would be more stable and long-lasting, but you’d lose the versatility. Sometimes the straight connectors come apart, but they’re easy to hot glue if you want them to hold better. This isn’t meant to replace a treehouse—it’s meant to replace sticks and furniture in the fort-making process. And honestly, it’s way sturdier than anything my kids have built on their own. I let them take the lead on the design, then step in to make sure it’s structurally sound and then we usually keep it up for a day or two. I really love the creativity it encourages and the fun memories they make in their forts.
