Good, if you dodge the traps for new players..
Three things to watch out for: 1-The little rings that you slide to tighten the grip may be open slightly at the join, so have sharp edges...dangerous near sensitive skin. 2-Be careful not to pinch the areola on the other side where the tweezer tips close together. 3-You'll have to close them snuggly onto the nipple or the little sliding ring will just slip back down, letting them go.
easy to use, the chain adds spice, great for a newbie
