This power supply works really well.
The battery and cover arrived on time, but the circuit board needed to connect the battery to the Gameboy was missing. I filed a complaint last week, but have not heard back yet.

Still have not received my product yet
The rechargeable battery feels like such a necessity, saves you money from buying double A's and works like a charm. Quality of the rechargeable battery is also another good factor about it too!
I can't believe there is no instruction for install this.
