Great product!

I am very satisfied with the power supply, it works for various applications. I was most impressed by how fast I received it in the mail. I ordered one from Amazon and ended up canceling the order after 3 weeks waiting for them to ship it. You guys are awesome!

Here in central Florida, the lightning capitol of the USA, we get frequent damaging power surges from lightning strikes on the power lines that has damaged electronic equipment. I inserted two isolation transformers to protect my computer and tv. So far no more surge problems.
