the first time i used this i thought the sensation was quite uncomfortable, but then after playing more with it i realized it was a MUST to apply lube or something to improve conductivity, it improves the sensation by 200%, seriously.
using it with dry skin is a big no-no for me. i love using one of these with the Flange, its simply amazing, im addicted to it.
The loops are a bit stiff and don't conform perfectly. They work as advertised and are easy to adjust.
Admin: They will soften up over time and use.
Great feeling with no detectable hot spots. Has enough adjustment range to fit around the base of the package and on the shaft.
Got the 4mm loops. The pulsing feels fantastic; and when the box is turned up the pain is is so great.
Without the rubber loops, I doubt that I would be using my Estim system as regularly as I do. It enables me to quickly get wired for pleasure, whenever the need arises. The loops also provide good conductivity between my skin and my device.
I have the 4mm loops. They are thick walled, comfortable, and durable.
