This one doesn't stick together at all. I already have 3 sets of these and want to add it to another device but can't trust it. set it up and it looks like it doesn't matter 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.
