With Mutebutton 1.0, the tongue stimulator was a consumable item and needed to be replaced every few months, at a cost of around €90. I expect it to be the same scenario with the 2.0 model, but probably more expensive.
K-bomb! So wait, we're going to have to keep getting sent new tongue tips every few months in the post?
Strong knowledge. I'd obviously pay whatever required to get rid of T. I'm not sure if I'd eat ass like @GSC , at least not on the regular.
