OK so my mausberry finally came. And it looks like it is different but not too different as the 3V LED pad is present so my concern is null. I can confirm that they have terrible communication and shipping took forever. I only got an order confirmation after I threatened to dispute the credit card charge. never even got an initial email saying my order was received.
