This product was a letdown because of the lack of instructions with it, the stiffness of the head, the size of the ring itself, and the loose packaging. However it wasn't a total loss due to the power of the mini-vibe.

Unless you (or your partner) is much thicker than average and you (and/or your partner) likes limited vibration, don't purchase the Inspiration cock ring. There are much better products on the market!

Overall, this is not recommended to buy. I was not satisfied and am pretty disappointed. To save anyone the trouble, I just don't think it is a "worth it" purchase.
