I do not recommend it, maybe only if you are experienced and know your vaginal muscles extremely well and want a discipline exercise, anything else can hurt you.
Obviously, it is not suitable for anal, don't even think about it.

The problem lies in the fact that the balls are connected with screws that create dents and form sharp angles, if the closure was curved it might have been fine, but with the current design, it can easily cause injury if you lose control or if they turn the wrong way. They also require extreme caution and very slow removal.

The material is hard, the weights are very good, but the string is simply unacceptable because you cannot clean it properly. Also, the distance between the balls is not correct, it is the same for all of them and it is so long that it can create a double knot, not a good experience at all. I didn't expect much for its price, but I didn't imagine it would be this bad.
