I had the option to buy a PPP and PurePower. The PPP worked fine for a few hours and then tripped my mains and kept doing that each time I tried to power it up. I sent it back the next day and the distributor has yet to get a new batch - this, after 20 months!
So I bought the Purepower and it worked fined for me until two months ago, when it started tripping my mains. It even tripped the mains when the wall outlet was on but the unit was off. No solution from PP so far, despite lengthy description of the issue. The distributor is trying to sort things out for me.
No, it's not my mains or wall outlet, i've got other stuff plugged in now, no hassles.
All I can say is that it's disappointing ...
