I had a packer (gave it away) that I got from them for $10, as it was a second. It was UGLY, but then again, not sure everyone's dick is that nice looking. Anyway, I thought it looked like a silicone foam (maybe) and found it hard to believe it was 100% silicone. OTOH, it was a second. But it was cheap. I don't think it was STP or pack and play. It was a "viper" I think, but not sure they have this model anymore.
