Your general opinion of this product.
Multiple I/O means you can connect it in a multitude of ways and software options for those connections works very well. I've used it as an interface, in the front of a tube head, a SS combo, in the return of a tube head, in the loop of a tube head and headphone only. Clearly the best sounding piece of gear I've owned and flexible doesn't even begin to describe what this tool can do.
The display screen is clear and big enough to see clearly, the knobs are smooth and very responsive, computer software interaction is immediate and latency free. It really does everything I need in a recording, modeling and silent jamming tool... and sounds fantastic!
