Well, total price of £7.49, I got the Pihut one.
It had five counters, each one splittable; new word!
Biggest decision of my life, use three or four.... I had sleepless nights

actually I am sad as I did think about it for a while!
I chose four, then wondered how to mount it. I decided in the end to wrap it in some walnut I had. Ignore the one bad join, you’ll see why I gave up woodwork... I cut off the four circuit boards, glued the four sides, sanded and waxed the sides and then fitted four small button magnets underneath.
Very pleased and I can put it anywhere on the bike if I don’t want to mount it the on the handlebar mount.
