I'm going to start this review by saying that I'm probably not the target market for these prosthetics; I'm not trans, it just adds another layer to play in my relationship, so I can't comment on how well it would help relieve body dysmorphia, etc. for trans folks.
But it is a very convincing prosthetic, it feels nice and has good weight to it. The harness works really well, though it takes a minute or two to get it hooked up the first time. The clip is also really good and it holds well with medical adhesive (I bought Skinister instead of the one suggested here simply because it was a bit cheaper per ml and I wasn't sure that I'd enjoy using the clip). However, once you get to understand how the adhesive works, it sticks like a charm. I've used it for hours whilst being pretty dang active and it didn't fall off.
When using the clip I didn't actually FEEL like it was there, which was great as I'd been worried that it would feel quite unusual.
This specific prosthetic is great for play as well as it is essentially a hollow skin (still pretty thick), with the shaft and ball inserts. It's not meant to try and replicate foreskin or anything, but it does give you that extra bit of movement to add to the fantasy.
The only thing I would say against this one, is that because of the hollow design with the inserts, it can end up almost... folding? quite unnaturally. It wouldn't be noticeable in a bulge, so not really a major issue, but if you're rearranging you can feel it and it's just a bit of a nuisance. Compared to the basic packer (that is solid, no hollow design with inserts), this is the only drawback. The basic one doesn't have the same ability to fold like that, but it's really a trade-off depending on why/how you want to use the packer.
