I really love the Kaylani doll, which is why I now have two of them
and you are right, in different wigs, she can have a totally different look.
Although only 70lbs (not sure where the 63lbs you mentioned came from), she's still quite heavy, so be prepared for that weight. Many people who buy high end dolls underestimate the weight and are forced to sell quickly after because they can't handle it, and that would be a shame.
I don't have much sex with my dolls, I like them more neatly dressed in my livingroom. Ashley, my new doll, has been with me for more than a month, and she's still a virgin
Sex with a realistic looking doll like Kaylani is very nice though, dim the lights, make sure she's warmed up (heating blanket), and let your imagination do the rest.
Thing is with pictures, they're static by themselves, so our minds don't expect to see movement, which is why dolls can look very real in pictures.
In real life though, dolls are static as well, so even if you dress and pose them very realistically, because she doesn't move, she doesn't convince your mind she's a real woman, at least, not longer than a second or two. If you see her in a glimpse, or the corner of your eye, you're convinced she's real, but as soon as your mind finds out she doesn't move, that illusion disappears. It's hard to explain...
I'm not saying she doesn't look beautiful, she does, very much so, and she can become as real as your imagination wants her to be.
A trick I've used on occasion is to pose her in way she wouldn't move much even if she was real, like recently, this pic, where she's reading a catalog:
Anyway, if you don't get your expectations up too high, a doll can be a very nice companion, and if you treat her with tender loving care, she can last many years without damage.
PS: don't know if Duracast (harder hands and/or feet) is available for the Kaylani doll, but it might be a good upgrade if you plan on posing her a lot and letting her wear shoes.
IMO, it's easier to put shoes on harder silicone than it is on the softer version. The rest of the soft body is superb!
