I've installed a bunch of them. As far as digital guages go I haven't seen anything better.
I don't like that they send the sensor and switch wires pre-termed. In most instances you will end up with a bunch of wiring to fold over behind the guage, or if they are too short you will have to cut and splice. Only gripe.
However, I prefer analog as they are easier to view at a glance and give you a better idea of rates of change.
