ive worn this for one year and I absolutely love it. Most comfortable device I have worn. We are saving up for a custom made device. But for now, this is a perfect device for me. https://m.dhgate.com/product/2018-h...resin/410285168.html#s3-13-1;searl|1558047028
Have one in small and one on large. Very comfortable and nicely constricting in the small size feeling like you have your cock locked in a warm wet pussy. Wife prefers larger so I can rub it against her, and the hidden lock ensures there are no sharp edges. Have it in surgical steel as well - lovely and smooth and a nice bit of weight!
