Just received mine today (although had to buy from another site b/c EF was out of stock ). I can tell right away that this is worth it. While the vibrations aren't rumbly like I hoped (was thinking something more in line with the WeVibe Salsa / Tango), the vibes are really, really, really strong for a c-ring. It is also well made - soft silicone, waterproof, strong but pliable ring. If you just want to mess around with c rings periodically and not use them to actually get off, buy the cheap ones. However, if you think you'll use the ring regularly, want to have a shot of finishing with one, and want your wearer to have the benefits of a true, tight fitting ring (e.g., prolonged, swollen erections), this appears to be the one to spend the $$$ on in this current market. Can't wait to use it for its intended purpose () with a review to follow.
