it works fine, but very dissapointed

the dildo itself attached to the machine works wonderful; However, I didn't realized that it does another function, I don't know what it is because it doesn't come with instructions, plus that the button to twist around is super stuck, then I pulled it out the "batteries" for then the sad part of realization that I broke it so it won't work, I wish this could have been instructed in a manual or something. Like I said, it still works pretty fine, except that now whatever fundtion it does it won't work for me anymore. The sad part about the whole thing, is that my order came and I just use it for the first time today T.T
