Bullet rocks, inner right is tight
This thing has got some serious plusses!  First off, the bullet is strong and the different modes offer a great variety of sensations.  The outer ring is also a pretty good fit.  I was concerned a bit by the flat back and angular cut as a result, but no real digging into the skin.  However, the inner ring is excruciatingly tight.  I happen to be well above average, if you know what I mean, and this is a common problem with products of this nature.  I managed to carve out the inner ring and get good results with the modified result.
