This was my first harness and it was complicated to use as far as all the "securing" measures were concerned. Installing the dong onto the plug was the easiest part; it worked well after that! If you have a smaller figure, then this would probably stay on better for you; it cut into my few humps, lumps, and bumps.

The outside is lined with vinyl, nylon straps, and the interior is lined with a low pile, furry/felt feeling fabric. I found the strap to be very, very thin, almost like a sheet of plastic. Great thing is that there are not any smells involved!

The straps are very thin and hard to hold onto while trying to put it on and securing everything; it would have been better made if at least one side was already secured. Once on, the straps are adjustable but not easily; every time it gets worn, the straps have to be completely re-adjusted to fit. The dong locks over a plug style insert; it only accepts Vac-U-Lock custom toys to fit it. There is no O-ring. I found a drawback to many of the Vac-U-Lock dongs being that they are mostly made out of rubber and contain a strong, chemical odor that never goes away.

The straps come adjustable, however on their largest size they just fit a medium build person. If you are larger, this strap is not going to fit you or if it does it probably will not stay on. I'm a medium build and the straps barely fit; they cut into my humps and bumps, which was rather uncomfortable from the weight of the dong.

The BEST thing was that the plug remained firmly locked into place, even with the dong. Its' weight meant that the strap wanted to fall down, so when the straps were tightened well it cut into my skin and was uncomfortable. I started to wear underwear underneath and over the top of it; yes, that's 2 pairs at once! Besides my discomfort, it did perform well and was very secure; I didn't have to constantly control the dong with my hands.

I wash the strap in dish soap, warm water, rinse, wring out, and hang to dry. Then store it in a zip lock bag. Wearing underwear means I don't usually need to wash the strap, only the dong and occasionally the plug.

Came in plastic box and plastic wrap/bag. No directions, self explanatory.

Need to wear underwear under it!

Difficult to wear but easy to guide during intercourse. Enjoyed the part of it being odor FREE also!
