Quality is sub-par. At least amazon lets you return.
This power supply causes an audible sound and visual static when powering the unit. This tells me the capacitors are cheap and low quality. Forget it. Waste of money.
Ac side is not well mounted in the adapter and pushes into the brick when plugging up. Can hear a spring rattle when moving the light-as-air adapter brick. Power brick is hollow which makes the system shut down when it overheats.
