This unit is fantastic for the beginner or to advanced. Its unique design allows for easy entry and insertion to a nice comfortable depth.
Then gently turn the thumb screw and feel yourself open up bit by bit, but in a gentle and manageable fashion. The special design is made for comfort and ease. This is easy to pop in and use, there's no training required for this baby!
Just use the screw opening and go for that extra stretch. Simple, easy, fulfilling!
