This is the first harness I've ever purchased. I am a transgender male, and so far, I've only used it for vaginal penetrative sex. It works nicely, but I'm sure it would work well for anal too. I believe it should work for everyone.
I've used it with the Tantus Throb and it works very well. It fits snuggly into the O-ring. https://www.edenfantasys.com/dildos/strap-on-dildos/throb

It has nylon straps with a neoprene-backed vinyl body and a silicone O-ring. The inside feels pretty soft to the touch. The body feels like a thin, squishy foam. I like thinner material because your biological parts can get closer. It seems to be rather easy to clean as well. The front is not porous.

It seems to be made fairly well. The straps feel strong and don't seem to loosen with use. It comes with a rubber O-ring, but it has snaps so you can use a different sized O-ring with a wide range of dildos, but I've only used it a handful of times and the body is unraveling slightly.

It fits very well. It will fit anyone with up to a 44" waist. It would be nice for smaller people because the straps can be tightened as small as anyone could possibly need it. I wouldn't suggest wearing it under clothes though; it probably wouldn't be very comfortable.

I believe it works as well as a harness could. It's not as comfortable as I'd like it to be, but that's while walking. I don't know how many people would be walking around while wearing their strap-on. It's very easy to put on and take off, and relatively easy to get toys in and out. It holds toys well and can be used in any position.

It is hand-washable (spot clean only), and then you lay it flat to dry. The front can be easily wiped off. The inside is spongy so it's a little harder to clean. I keep mine in the original box.

It comes in a nice box in a plastic package, with a mannequin wearing the product on the front of the box and also on the back with a dildo in the harness. It does not come with instructions but i think its pretty self-explanatory. It also has a lot of information about the product on the box.

It gave me and my partner at the time a very nice enjoyable experience. Being trans it really helps me feel like a "real boy."
