I like that I can tease myself while driving or out and about. The power is very strong, and it fits well under my underwear. Every frequency is very enjoyable, very comfortable. When I turn the function to the maximum, I am very satisfied with the pleasantly tingling feeling all over.It's very easy to use and I'll feel like I can't do without it afterwards I want more. I also like when I am out with hubby he can tease me with it also. The power setting of this is fantastic and when I play with several frequencies, it is very strong and drives me crazy. Also very discreet box!
