You are buying the looks most of the time. I have one that looks so freakin real it's not funny but the feel is anything but realistic. Of course same can be said of most of the strokers (Fleshlight, Tenga), some feel a bit realistic but still, they are not the same.
Most of what you are paying for is the material. If you look at my review of the Noches latinas big ass and vagina
you can see just how big it is, compared to my hand. That's 14 pounds of UR3, I am guessing it will sell for about $150 or so. That's 10 bucks a pound! Of course a Fleshlight sells for around $75 and only weighs a pound. Go figure.
It all comes down to what you want to look at, a tube shaped stroker or a mold of pussy and ass. Something else to think about is storage. I can hide my Tenga Flip Hole in a drawer but the Noches latinas big ass and vagina has to be stored in the box and kept in the garage.
