Query: Burned Up Unit!!

This item we *thought* would be an awesome alternative to batteries but it wasn't! After a few weeks of using it, it actually burnt up my daughters Leapster, We were able to exchange the Leapster threw the company but still out the $25.00 we paid for the charger when we got it. I am not sure if I am going to purchase another one either. Company says there has been a handful of complaints about them...we will see if they actually upgrade them before I do actually buy a replacement.
