Opinion on this A/F gauge

I heard that this was the best A/F meter. Anyone ever use it or have ?

Why is this any different from those pretty blinking lights gauges? For me, digital readings is the way to go.

Because it doesnt blink like the autometer one. At idle it just stays and when you hit the gas(doesnt have to be WOT) it moves and gives you your reading. This is just what was told to me by some one who used it.
