I purchased the Cone Large Firm in hopes that riding it down to the base then sitting on it would get me opened and relaxed enough to insert the H-Bomb. Despite bottoming out on the Cone's base, I haven't been able to swallow up the H-Bomb yet. The tip of the Cone opens up the third ring and works its way into the sigmoid colon. That's a great sensation in combination with the wide stretch at the base. I can see this toy becoming my regular warm-up toy for both width and depth, as well as the go to for a quick one toy riding session. However, what keeps it from getting five stars is that I think the taper and tip could be more aggressive while maintaining the same or slightly longer insertable length. That would mean more of a stretch at the deepest point, which would intensify the overall fullness.
