Query: There is a very big flaw in this product

I got my AT&T Caller ID model 326 about a month ago, and i've had to change the batteries 2 times already!!! That is rediculous. It takes 3 AAA batteries (not 2 AA batteries like it says in the description). And yes, i did buy brand new batteries both times ;) This Caller ID box would be great if the batteries lasted longer. The other review for this product says that it "lights up when the phone rings" which is false. I think this guy was talking about a different caller ID box. Mine looks exactly like the picture up there.
