The Toy is not easy to use but if you look a bit busy and then taking at the beginning of time to work it with the setting and the placement. Helpful is a second pair of hands that optimizes the adjustment if the product is introduced. The partner has great insight and it's great fun to try the toy for couples. The man can penetrate easily and the grooved surface spoiled him just like me in the act. Also suitable through the material waterproof and thus for water games. Of course, the toy can also be used with a dildo or vibrator alone or with your partner making no less fun. The surface is pleasant and without annoying edges or seams, absolutely odorless and thus in the usual Lumunu quality, the arms are amazingly powerful, yet well adjusted.
