I don't know whether this is supposed to be strictly about the doll or the entire ordeal. I will include everything in order.
Support experience: Good. Before buying, I asked whether there's a way to get the doll with smaller breasts. Support was responsive and courteous. (Sadly, JX Doll's options for this request are lacking, but that's not BetterLoveDoll's problem.)
Purchase experience: Good. There's really not much to it. You buy it and it eventually ships. The only thing I can really say is it took longer than I expected to ship, given that it was supposedly in-stock.
Delivery experience: Good. The doll is packaged carefully and does indeed come in a non-descript (but obviously large) cardboard package.
Inclusions: Comes with some very minimal lingerie and a cheap douche. The head comes detached and there are no instructions, so I had to look up how that worked.
Quality: This is my first doll, so I don't have anything to compare it to, but overall I think Boa's head and the body it comes with are excellent. The head is the entire reason I decided to go through with buying the doll; it's absolutely gorgeous and the real product isn't far off from the glamor shots on the website. I will mention that the toes have no wire in them, so they just jiggle comically whenever she gets nudged.
Advice for first-timers like me: Be prepared for how heavy the doll is. I can deadlift an 85lb barbell without much hassle, but carrying a stiff TPE human body of that weight around the house is different and can strain your muscles. Plan your attack in advance when it's time to wash and/or douche.
You will want to read up on the website's care/maintenance page and invest in some of that stuff as early as you can so that you have it ready.
Her hair comes braided, and it starts out in a wig cap which you should keep on until the head's secured. Otherwise the hair will quickly get in the way. She has A LOT of hair, so once you unbraid and start combing it you can expect plenty to come out, and you're gonna run into knots.
