Should I get the Timemore C2S chestnut?

I brew moka pot coffee daily (bialetti moka pot) from pre-ground beans usually from devans. I drink black coffee and I also have a vietnamese phin filter. Is it worth it to get a grinder? What all things should I consider while selecting a grinder? I only wanna make moka pot coffee and phin filter at max. Also, any reviews about the timemore c2s and would I notice any significant difference?
