Great job on this one lovesnse....  I wasn't expecting too much but,   after a test run I am quite impressed with the performance and versatility of Diamo.   Having previous c-ring and c-sling experience, slipping into it was a breeze. (The larger men may have a bit of an issue due to tightness).  During control I was very impressed with the sensations I was receiving.  At low levels I it was a pleasant hush style rumble targeted at my perineum.  As the vibrations increased I felt the sensations more towards the base of the shaft of my penis.  It was almost like dual zone vibrations similar to edge.  Was thoroughly pleased to find that vibrations weren't only going to be felt in one area.  Only suggestion I would make is bigger size hole for the more "gifted" men, as this may be a bit tight for some.  That being said,  Diamo will be an amazing enhancement to a toy playtime session  or solo pleasure sessoion as well for in person playtime with a partner.   Knocked it out the park with this toy in my opinion.  This one will surely be on top of the toy pile..
