Expert reviews

The performance of this unit was simply flawless. We had a clean pass for Gold efficiency both times, so no points deducted there. We had no issues with any of the minor tests I run, so no deduction there. The same goes for the better than excellent voltage stability and the super low ripple I had to zoom in to even see...
