This one doesn't hold together at all. I already have 3 of these kits and want to add them to another device but can't trust them. does not fit into my existing set and looks the same as it makes no difference at all. 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.
