Similar to the Darn Tough socks analysis, this is useful for reference.
I currently have the MSX201. It’s tinny and the plastic lid cover keeps falling off. Think the S100 is the equivalent.

S100, S200, S600 roughly the same rectangular form. There is also a card-shaped one (reciprocating, 往复).
S101, S301, S302, S700 are all tri heads. There is also a ‘Pro’ in this category.

Idk how many grams they are. It didn’t say.

Ceramic blades are useful because more skin friendly.
Brushed motors are the regular ones, brushless quieter and have less friction, electroformed mesh is opposed to stamped sheets which is supposedly better.
