It does it's job. It handles it's full load really well, no hiss, no loss of power, no interference. Everything is good.
My main thing is it's build quality. Mine has been beaten, fell, but the main thing — it has been drowned in boiling hot water. I had a flood in my apartment with hot water completely covering floor, and of course my pedalboard was like a surfing board there for several hours. The power supply was tied to the bottom of the board, and connected to power.
Not only did this thing protected all of my pedals — it survived that. After the place dried up I was surprised beyond belief when I plugged it back in and it worked like a charm.
Considering it's price and built quality it's a stellar product.
