As of this writing is the plug for the first time in use - it is very well formed, no edges and feels - once introduced - really good. Even while sitting very comfortable. This size and shape of the plug is suitable for longer lasting certainly use. First steps convey pleasant feelings, viewed from the rear of the crystal is very beautiful to look at. The dark red color of the plug blends well with the shining stone - for each carrier / each wearer a real ornament. I'm going to plug - if at all - only remove it after a few hours, it fits like a glove.
From me an absolute buy recommendation - I'll probably still set the plug in other colors, because it is a really nice part!
Addition: After the first night with the plug he will probably accompany me also working on introduced - the long-term test runs so far very positive!
