Here's my first impression.
It's smaller than I expected.
Apparently the colored lines embedded in the sleeve are semi-rigid plastic. I think to help it keep its shape. because it's so floppy. The sleeve Cannot be turned inside out because of the rigid plastic embedded in the sleeve, but it's supposed to be reusable after washing it and junk. Lube is hard to coat along the sides, and it pools at the top while you apply it. The best way to make sure it coats the entire inside is by sticking your finger into the closed end and pushing it as far out the opening as possible, making sure to rub against the sides in the process.
The container the sleeve comes in is designed to have a water reservoir for when you dry the thing off. You just rinse it out and put it in the container, leaving it upright so that it drip dries and the water collects at the bottom. Unlike their cups, this one's got a wide enough opening that it can drip dry. That's my best guess. There's no instructions provided on how best to dry this.
As for use? It's okay. Nothing super amazing about it besides the fact that it literally twists and contorts with vertical motion. It's very soft. No firmness or rigidity to it. It's pretty nice, but I still prefer the Misty egg for its unique texture. I doubt I'd get the other 5, even with if I had the extra money, but If they make one of these with a Misty texture, we're in business.
Because the Spinner is one-ended and it's long and soft, there's a chance the top end will balloon out from trapped air. It'll queef out something fierce unless you squeeze it AS you insert. If you try to get the air out any other way, lube goes everywhere.
