The product is very hard, so it can be a bit uncomfortable getting it in but once 'in' all is forgiven and it gets down to business :-)
It's very secure and can be worn for an extended period without any trouble.
It's very washable.
Also, although it's marketed as a P-spot massager, we suggest that you try it as a g-spot massager - if her anatomy and the toy are a match, she'll enjoy it, too -)
