I received this Monday and tried it that evening and I love it! I have pretty tight balls, so tying them up and then having my mistress abuse them has always been a challenge. I like to play online and on the phone, so I need to be able to handle the logistics myself, which makes it even more challenging. I was able to get this on pretty much out of the box and the accompanying ball is a decent weight. My mistress had me jumping up and down with it and it was a good intro to the world of stretching. I do want to try heavier weights, but this was a great first step. I was also instructed by mistress to put the ball weight on my nipple clamp chain and that was fantastic too!
