Purchased recently.
This was my first power system.
The great advantage of the beast in addition to removing the buzz and Co. is that it sends 3A.
When you have a lot of pedals is a great solution with respect to price.
It takes very little space and can feed the 9VDC and 18V with an additional cable.
I invested in any single (pp2 + and fuel tank jr) Diago but the system did not disappoint me.
