anyone have problems with their Learning Resources cash register?

So we've had ours for a few years now, it was getting wonky so I thought it was just batteries. Well, tried new batteries and that didn't do the trick. Tried MORE new batteries and that didn't work either! It gives me the welcome message and lights up but when I push all the buttons, nothing happens. Tried the reset button too...so I figured it just died.

So cut to this past weekend, it's my DD's bday and I get her a new one. And THIS one is all wonky too! Tried the new batteries and it only gave me the welcome thing. I swear, I just bought the batteries at Target!

Has ANYONE else had issues like this? Do I just have two really weird registers?!?!

Thanks!
