DMSPL

I have a good time with it. The stimulation is such that I can use thin lube based for the pink section and not worry about the hard section needing a thicker lube, which would probably mute the softer section. While I have not tried this one specifically as such, I do not recommend using this type of sleeve design as a Stroker (Soft Front / Hard Rear) as a large and abrupt change in firmness can be problematic without enough support.

The textures inside seem pretty lacking compared to the pictures on the box, like fast food burger, but it still gets the job done just fine. While I tend to prefer soft and lower stim, I was just expecting something more novel with the textures.
I think the thickness really helps do it justice.

It doesn't seem like it should be very tight for me but the pressure is still very high. I think I am too sensitive for it or the material is just too thick for me. I really like the feel of the material itself.

I'm not very familiar with cock rings but this is painfully tight for me. Maybe from the thickness of the material or I am just too sensitive. I mostly bought it to check out the material. The material itself seems very nice, so I recommend checking it out for that if you know what you are doing.

The tunnel itself doesn't blow me away but I would like to try more designs like this. The hard outer layer is not very oily so it makes for a good unboxing / out of the box experience. The inner layer is also nice and thick. While it is not a favorite of mine personally, I think it is highly recommendable and a quality Dual Layer.
