I had the Voodoo Lab Pedal Power 2 Plus for a few years and was extremely happy with it but I needed something smaller to power my currently downsized pedalboard. Based on my positive experience with Voodoo Lab, I decided to buy the ISO5. And I'm really glad I did! It is very well made, fairly light and has a small footprint. The quality is of the same high standard as the Pedal Power 2 Plus, and I like the fact that it still being made in the USA. It shows that unlike many other companies, Voodoo Lab doesn't want to sacrifice the quality for the sake of lowering the price.
