FlexiKnot 6"

I wasn't sure about the adjustable waistband at first, but it actually fits perfectly and stays put. The suction base held firm on my bathroom tile, which made solo play much easier. Definitely getting good use out of this.

The flexible keel core is a game-changer—finally a strap-on that actually bends to the angle we need without fighting it. The adjustable waistband held snug through an active session, and the suction base stayed put on the tile floor. Assembly took maybe 20 seconds, no tools required.
