I bought it since I use a very simple pedal board of 3 pedal (boost/overdrive, wah and tuner) together with a pedaltrain metro16, and this power supply is perfect for it! super light, which makes it easy to carry around to gigs, and also has never fail. It has some stickers to make it attach to the pedaltrain, and it fits pefectly! It does the job very well, I recommend it if you looking for something light and effective.
