Well they were bought since Christmas, so I'm presuming they are. Both have the 5A power supply.

They differ from the pictures on eBay and amptastic.com in that the top and bottom have a bevel routed into them. Other than that, they appear identical - blue illumination, just a power button and volume control on the front.

On the rear, there is no amptastic.com stamp, but inside the circuit IS stamped 'amptastic'.
