They are awfully good. I got a pink lady years ago and wore a hole in it after lots of use. I got an ice one and original pink, and the pink wonder wave was way too tight for my 6 inch girth. I did clean them as directed, but still the clear one got cloudy, and worse, it has strange spots on the inside, and I don't know for sure if this is related, but I've had hellacious itching right down the middle of my scrotum and behind it, and tried every antifungal I could, and after over seven months aggravation went to the doctor, and it still is not solved. There is no visible outbreak on the surface, but I have scratched myself raw, and wonder if it might be from the fleshlight.
They run about $60 for the case and insert.
