I bought this power supply on a whim, because I had a Powerplant JR and around 9 pedals that needed powering. Coming from the JR, I had to use ABY cables to create sort of a daisy chain to power multiple pedals from a single output, so that's why I bought this - more outputs, isolated, promising looks and features.
I do not regret that decision. This supply is the real deal - it's truly isolated, it has no hum, no noise, providing stable power to my pedals (even better than the JR, which sometimes had fluctuations).
It is way smaller in reality than it is in the pictures - I was expecting a bigger power supply altogether, since the JR is quite tall and wide, but this one is thin and small. Albeit small, it feels solid, made of metal.
The only complaint I have about it is that I have had a hard time fitting it in my Harley Benton pedalboard, because on the JR, I used the angled ends of the cables in the pedals and the straight ones in the supply. Now I have to go angled in supply because otherwise they wouldn't fit in the pedalboard, so keep this in mind if you have a tight space there, you'll probably have difficulties fitting the cables.
Oh, also, the JR came with way more cables than the ISO-2 did, which was a bit disappointing.
Other than that - this supply is golden. Comparing it to my T-Rex Fuel Tank Classic, I see no reason to go the extra miles and throw the difference to go for the T-Rex, now after using both the Jr and the ISO-2 Pro.
