So it seems like the batteries would die or be close to dying every 2 or 3 uses in my vibrator (it takes 2 AAA batteries). I'll probably use it about an hr every use. Well last time I went to use it, I put in fresh batteries but never got to actually using it because something came up and I got distracted. Now it's 2 days later and the batteries are dead, or at least low enough to not be able to power the toy, even tho it was never turned on with new batteries! wth??
