I’ve used monkeybar’s xsleeve all day stretcher (ADS) for about 18 months. I like it.
The xsleeve is a long silicone sleeve with a small cap that covers the tip of your penis. You can wear it alone, or add a strap and rubber bands to apply light tension. When you order it, you get to choose how soft you want the silicone sleeve to be. I ordered two: “soft thick” and “medium”. The basic set costs about $50.
I found the “foot cord” which is shipped with the product to be useless. So I went to amazon and bought a simple knee brace, and tied rubber bands between the knee brace and the small cap on the end of the xsleeve. When I wanted more tension, I added a rubber band.
It does take some time to get used to wearing it. Every time you take it off and put it on you should check for tears on the ends of the silicone tube, and trim them off with a pair of scissors. Otherwise, the tear will get very large and ruin the silicone tube. Replacing them is expensive ($20 or so). The softer the silicone compound, the more likely it is to tear. The soft one tore after 6 weeks or so, and I am still using the medium one after 18 months.
I wore the “soft thick” tube at the start, since it was more comfortable. Now I only use the “medium” one. After you are conditioned, it is easy to wear it for hours on end, and can be worn under clothing without being too noticeable.
It is a pretty unique product. The theory behind an ADS is that it prevents your penis from turtling, and lets it heal between PE sessions in a stretched state. On its own, I don’t think it would give you any substantial gains. But if you use it as an extra step in a routine that includes exercises, hanging, or pumping, you might gain faster than you would without it.
Live long and prosper.
