This one doesn't hold up at all. I already have 3 sets of these and want to add it to another device but can't trust it. The forts don't fit. in my existing set and looks exactly the same without any difference. But even with the part that comes with the kit, he can't hold it himself. The part comes out effortlessly and I'm glad I could see that before I put any of my devices in. Sent back for a refund. The garden did not live up to expectations.
