A while back I recieved a question asking me to review the plethora of prosthetics/packers I have used over the years.
I’ll give each a rating out of 10, with 10 being the better end of the spectrum. 

Note: This is a work-in-progress; I can’t sit down and write all of the reviews at once. Thanks for your patience. 

Homemade Condom/Gel Packer: There’s a first time for everyone, and mine was right here. As far as I’m concerned this still feels much more realistic through underpants than some of the more pricier store-bought packers available. Not too much to say here; doesn’t look realistic, but feels good and you can choose what size you’re comfortable with.
4/10

Novelty Sticky Penis: This was, when I was very young, my first ever “bought” packer. It was sold as a novelty, and the texture and consistency is exactly that of those sticky slapper hands you had as a kid. I had to powder it every time so it wouldn’t stick to my harness, and it was actually bright pink – but it worked and made me happy at the time. I was underage, and did not have any way to order online. This sufficed, but I wouldn’t reccomend it. (Link to what I’m talking about)
3/10

Mr. Limpy: This was the first proper packer I bought. I probably can’t say much more than anyone else has; they’re affordable, pretty realistic and come in a few different sizes. I couldn’t use any but the “Extra Small” version without feeling like I had an uncooked sausage in my pants. Does the job well, and I still use this particular packer if I am going swimming or doing particularly acrobatic activities. It stays where I put it, and it’s too large to look obscene under tight clothing/swimwear. You can easily make homemade STPs out of these, too.
Cons: Lacks the realism some other prosthetics have, can often feel a bit too squishy, needs thorough cleaning and powdering so it doesn’t get sticky.
5/10. 

MAN-GO: This was one of the first STP’s on the market which wasn’t simply a medicine spoon recipticle in a Mr. Limpy. What I really liked about this product was the recepticle; it was much smoother and easier to use than the medicine spoon I had been using prior. The packer itself was just a Mr. Limpy, although I purchased my MAN-GO when they first came out, so I can’t really comment on how they are now (or if they even exist?)
7/10

GV Sailor: This packer is probably the best in terms of realistic feel than most others as the core is a different density than the outer softer skin, giving it a realistic feel and weight. I never really used this packer much however, due to me not being able to find a comfortable way to pack with it. I was used to a smaller packer back then, and I think this was 4″ instead of 3.5″ that I was used to. It’s on par with the Mr. Limpy with regards to realism when looking at the prosthetic, however feel is far far better.
7/10

Peecock Generation 1: This, as it stands, is by far the best prosthetic I have had to date in terms of how it sits in my underpants, how it packs nicely without an obscene bulge and how easy it is for me to urinate with it. I forget I am wearing it. I never have to think about lining anatomy up, or accidentally messing myself. It also works well enough in bed for sexytimes, seeing as it’s a Pack, pee and play.
The cons with this particular product are the severe lack of realism; there aren’t as many little details on this prosthetic as there are on say, Mr. Limpy’s, but the ability for it to work so well in other areas surpasses this inconvenience for me. I also did not want to have a giant prosthetic for packing, so I opted for the smallest they had – which then made it a little too small for bedroom use.
8.5/10

Freetom 4-in-1: This has been thoroughly reviewed both in video and in pictoral format HERE and HERE.
