I tried both FLIP ZERO white and black.
I got good feeling with white but found it a bit heavy (comparing to air-tech or even more , spinner) and not so easy to clean (because of the hollow sphere retaining fluid).
However black was near perfect, very good feeling, still a bit big and heavy so I remove one star as I know TENGA will release even more incredible product in future ;)
Ottimo prodotto , ma si sente la mancanza di un calore vaginale ...
Rimane cmq un buon prodotto che può essere facilmente igenizato mah ripeto si sente la mancanza di calore vaginale ... .
