It is nice and easy to set up. There is a menu where you pick the colour, how it is displayed ie in a bar graph or circle etc etc. I only had a play for a few minutes and it seems easy enough and I’m not great with this kind of thing.
It has 6 pages that you can configure differently and you just swipe the page to change.
They do a round 52mm one that I was going to get.
I want it to display RS on power up but think that maybe a step to far for me.
