You're not going to find a more realistic packer for the price. The shaft swings like the real thing, and the movable testes are a bigger, more lifelike size than most other packers' (and fun to squish). Little details like the skin folds near the glans (on the cut version) and the texture of the scrotum add to the realism. It's also not too sticky like some packers are. It's the best packer I've ever owned, and the price can't be beat.
Great product so far. I've successfully used the STP function many times and it packs well. There was a tiny chunk of silicone that ripped off at some point during daily use, but you wouldn’t notice the divot unless you knew it was already there. Well worth the money!

This is my first packer so I don’t really have anything to compare it with but I am really happy with it. It feels so much like a part of my body that I don’t really notice I’m wearing it and the gender euphoria is just unreal.
I was slightly worried that it would be too big but I think it makes a bulge that is proportional to my body. I’m 6 ft tall and fairly broadly build for reference. I will probably get the smaller one as well as I’m still in the process of figuring my gender out so I would love to have one I can wear when I’m out and about that is a little less noticeable. I wear it with Axoloms harness which works perfectly.
I live in Europe and was pleasantly surprised with how quick and smooth the delivery was once the packer was shipped. All in all just a fantastic experience buying my first packer and I will definitely be back for more. Uh and I loved the little keychain I got as well!
