The manufacturer did a very poor job of implementing the voice box into this doll. The voice box is faulty and fragile, the wires are exposed as well, which is just plain careless. I ordered one Linn Thomas Doll and it didn't work at all, then I sent it back for another one and that one didn't work either. For the few loops where the speech actually worked, the doll sounded like a Man instead of a horny woman. The voice is deep and will make you laugh instead of getting you into the mood. How could the manufacturer screw something like that up? The mouth is virtually impossible to get into. You'll need a whole lot of lube and you'll need to stick something very thick into the mouth and let it set for a long time to loosen it up before you can even attempt to insert yourself. And even after that, it'll still be difficult. Why do they make the mouths so impossible to get into? The vaginal entry is kinda tight too, and the nubs just make no sense. I mean, it doesn't exactly invoke realism. All in all, I would't recommend this product. The electronics are faulty and chances are the one you buy isn't going to work (I've gotten two and both of them didn't work). I'm glad the guys above me enjoyed this product, but I don't see how they could have. In short, this thing is junk. Buy something else.
