So obviously since this is an STP the shaft isn't going to feel super "natural" due to it being hollow. I did order the STP rod along with this, which I do think is a bit short towards the tip but overall helps it feel more "natural." Despite the actual meat and bones of it all, I think the feel is fairly good! It's soft around the shaft but firmer around the testies. One minor irk I have with this so far is that due to it being silicone, stuff like hair and fabric stick to it like crazy, even after washing. The tip of mine is a touch roughed up after only a few hours of use so I can't say for certain how long the product will last with daily use. Finally, I do wish that there was a tad more variation in the colors since I personally have extremely pale skin and already knew the lightest color wasn't going to match well (even accounting for darker skin around the genitals) but I think C1 is a touch too yellow for a vampiric-white boy like myself.
Okay, now the things I did like! For the price, it is a very good starter STP compared to more expensive prosthetics and the team was EXTREMELY kind and reached out to ensure my product was delivered since there were some minor issues with receivable hours. Love the communication. I do think the molding looks great and very realistic if youre not looking at it super closely and I'm certain that they will only get more realistic as new products come out. The length/girth was absolutely perfect for me as a 5'5" skinny guy. Not too thick, not too thin. Fits perfectly in my pants and packing boxers and doesn't feel uncomfortable to walk/sit in.
Overall, I think if you're looking at a beginner STP packer, this one is decent. Don't expect it to last forever, though. I will be returning to this shop for more prosthetics, though! :o)
