I've been using Monogram (and before that Palette) for a few months. I can no longer edit in Lightroom and Capture One without my Master console.
The engineering quality is beyond-supreme and the included configuration software is a work of art. The Monogram support team was super helpful and responsive when my shipment got stuck at the border and resolved the issue almost immediately.
Such a great product, I'd give it 6 / 5 if I could!
