the silisleeves are nice quality and comfortable for the most part. i say "for the most part" because after having it on for awhile, i noticed it starts "digging" into the skin causing numbness and pinching. i believe this is from the openings of the sleeves having a straight edge when it is made. i have used silicone cock rings with a straight edge at the openings and have had the same experience with numbness and pinching. i found cock rings that were more comfortable wearing for longer periods of time with no numbness and pinching. these cock rings have a curved edge at the openings. although, i do not have the fat tire cock rings from the mos shop, i noticed in the picture they have a curve at the openings.
my suggestion is, if it will be possible, to produce silisleeves with curved openings on both ends. imo, this will make for a better, more comfortable experience. of course, if the user cuts the silisleeve, there will be a straight edge where it is cut. this could also open the possibility of offering 1 and 2 inch silisleeves. personally, i cut and use a 3 inch sleeve and a 1 inch sleeve. sometimes, i mix it up and use a 3 inch sleeve and a 2 inch sleeve, so on and so forth... it just makes putting it on much easier and convenient compared to a long, one piece sleeve.
