I have one and did a review a few years ago. Good points: ships discretely, hangs well, 3d testicles are very very nice, realistic color (for a packer), realistic look for a packer, silicone.
Not so good: HEAVY, a little hard to pack (I'd recommend jockstrap).
We are talking "basic packer" the $90 one not the prosthetic.
I'll see if I can find my actual review.
