Pros:
Charges 10 pedals at once
Has on/off switch
Fairly compact
Great price
Removable cables - you only need to put in as many as you need to use (less clutter)
Cons:
Plastic casing suggests less durability
I was looking to power about 6/7 pedals on a pedal board but didn't want to pay powerbrick prices. Andertons home brand power block is a fantastic solution to my pedal board problems. It is a small and compact unit with an on/off switch (can be left plugged in onstage) and can power up to 10 pedals at once. The unit isn't noisy as far as I can tell, saying that, I've not really tested it all that greatly. The only thing I can see as being a problem, the unit is a reasonably thin plastic construction, which I can't see lasting for a great deal of time, but for the price, I'm not complaining.
Bottom line - If you don't want to pay though the nose for the big brand power solutions, this is a great second place.
