Compact PSU with five 9V DC outputs (except the center one) and 120mA each. All outputs are galvanically isolated.

What's inside the box:
- Five 1ft cables with straight/right-angle plug
- Five 2ft cables with straight/right-angle plug
- One Y-cable to feed a 240mA 9V pedal (no possibility to feed an 18V pedal)
- One 3ft daisy chain
- One manual

The pros:
- Very compact PSU that can be accommodated in any pedalboard.
- The 120 mA are enough to power most pedals.
- The Y-cable allows you to a more power-hungry pedal (but you lose an output)
- Incredibly effective insulation of the 9V outputs (I place the PSU on top of the pedalboard, just below the WahWah, which is very susceptible to interferences)
- No noise, not even with the Wahwah (Vox 847A)
- The price is unbeatable (even considering shipping and handling it's less than $50)

The cons:
- No power switch
- Non-detachable power cord

Personally, I connected it to a power strip with power switch concealed under the pedalboard and whatever will be, will be (the power strip and PSUs are fixed with heavy-duty Velcro).

I wouldn't hesitate to buy it again, given its price and performance.
