Summary: I'd say this is beyond value for money. Good quality, most importantly on the included cables, and seems to work on most pedal brands/types. Most of all, it really simplifies having a pedal board, since this one unit can supply most pedals with power, without noise.
Upsides: Small, so fits easily on any pedal board. Lots of cables included of generous length and quality. Cheap. Noise reducing: a friend had trouble with noise from only two pedals, so he borrowed the PP Junior with its included cables from me and the noise was gone.
Downsides: Cables won't necessaily work for all pedals, at least for my SA soundblox 2 manta. However, I have a dunlop, boss and digitech pedal as well, all powered by this one unit, so it certainly is versatile.
