I don't have that exact toy, but I have one with a similar construction, with a vibration motor at the base, and the vibrations are definitely feelable at the tip, albeit they are obviously weaker than the base. Whether that is enough for you well.. I suppose it would depend on how strong the motor is and how strong you want the vibrations to be
I’ve never used a silicone toy and I don’t know how bendable it is. How much will it adapt to my body?
That would depend on the firmness of the silicon used.. couldn't say much without having held the toy myself
