As someone that has used the Tenga Spinner, the Bobble really feels like an upgrade, the material seems to feel better, and doesn't feel as sticky after multiple washes, it's ability to fully turn inside out is great too, making it by far the easiest to thoroughly clean and dry
As for the feeling, it feels amazing, especially when you get used to manipulating the cubes, it almost feels like an actual tongue, and it unexpectedly works really well
It's great, honestly up there with the Spinner as one of the best in the market in terms of an easy to clean, and accessible to for both the experienced and the new
