Felicita Arc v.s. Timemore Nano v.s. Weightman

Test and compare Felicita Arc , Timemore Nano and Weightman.
The Best is Felicita Arc. But it's also more expensive than the others.
I don't recommend both The Timemore Nano and The weightman (Maxus).
Pay a little more for Felicita Arc, it's worth it.
Weightman (Maxus) give slow responding or don't response at all for 1-2 beans.
Timemore Nano is not accurate enough and due to the calibrating process, I think nobody can do it. (You need the weights of 20g, 50g, 100 g, 500 g, 1000 g and 2000 g with you.)
