This might not help to much as I'm not sure about the Slider
extender but the
VLC works great with the
SG. So if the Slider
Extender has an end like the
SG than I think it will work just fine also in regards to the skin you can slide over your head already is good (the more the better) it will help you get a secure fit with your
VLC plus it will definitely give more skin in just a short time which will allow you to get an even more secure fit. Keep in mind that the
VLC is not for foreskin restoration but it does produce more skin which is vital to length gains. Also just wanted to note, consider wearing the
VLC as an
ADS (using the provided leg strap)as it works great in keeping your dick stretched all day after a length workout.
