I have been using Voodoo Lab power supplies for many years (PP2 plus, ISO-5 etc) on my guitar pedalboards, and have always found them to be excellent.
I was putting together a bigger board, and decided to get a Mondo as it would be able to power the whole thing, including a couple of large draw effects (strymon timeline and mobius).
As expected, I was able to power everything from its own, isolated output, with no background noise or earth hum.
I was very happy with this unit, until a couple of months ago, when during a rehearsal half of my pedals stopped working. I discovered that one bank of outputs (normal 9v side) were completely dead. There are essentially two power supplies in the unit, one side for normal 9v pedals, and the other for higher current outputs, that are linked together, and after some research online, I found that one side failing can be common problem with the Mondo.
Thankfully, Voodoo Labs products have a long warranty, and I simply returned the unit to Thomann for repair.
Although I got the unit back as good as new, I was without a power supply for almost 5 weeks, and my confidence in the reliability has been undermined. There are a number of similar power supplies available from companies such as CIOKS and Strymon, and if I were buying again I would definitely consider one of those options.
