Analog and not digital display

This compressor is lightweight and not very powerful, but it's fine. It works much better when the engine is running. My only concern is the description: I already had a RING, similar model, but which displayed digital. This is exactly what went wrong after two years of occasional use. The compressor always work, but we do not know at what pressure. I had not seen in the model description that I just bought that information are analog. It may be much better - we'll see - but this difference was not highlighted (or I did not pay enough attention).
