Works well, outside got a bit tacky.
Neat design, the spinner part allows for great pressure when using this device. I did find that the outside gets a bit tacky with use, corn flour on the outside does stop this but needs to be applied each use. I prefer the devices with an external housing, such as the flex, but the design of this doesn't allow for that. A good backup device, but not my go-to toy. It also lacks a drying stand that other tenga devices come with, which is a shame. It's nice to look at.
