Dude, that's what i was saying earlier, it's all just the same product out a different factory gate. On one hand, i'm kinda surprised you got peel on what is marketed as such a high quality product, and quite so early. (If you wanna try and fix it, you need an adjustable heat gun and a spoon. You play the heat gun over the skin till it just starts to melt, then smooth it down with the back of the spoon. On the final pass, use a bit of cloth to reintroduce some texture to the skin. Obviously it might fuck up so go slow, and wear a mask for the fumes, the stuff is fairly horrendous when it melts...). On the other hand, i'm not surprised, the sex toy industry is the epitome of snake oil salesmen, as the products are technically not returnable. As long as a butt shaped lump of TPE with a hole in it arrives, as soon as you open it, it's judged 'used', and it's instant profit.
Pretty certain those 'Tantabosom' (wtvr) are just gel filled breasts. That's what's on the high-end dolls, Tanta are just being clever with the marketing and inventing some word salad to make it sound better.
IF you STILL wanna spend good money, i would recommend looking into WM's range of torso's (like the one you pictured), they're a reputable manufacturer, as much it's possible to say that about any Chinese business, that is.
i don't use torso's myself (though i'm kinda tempted to grab for now), but i do know dolls, and i've pretty much come to the conclusion that i'd rather have as many lbs of TPE for my buck as possible, and have more than one model for variety’s sake, than blow the whole budget on a single, non-returnable, item...
