TIMEMORE - D40+ / SD40 V2

I personally use a timemore go as my daily driver. It's a portable grinder with built-in battery and motor. I think timemore have 3 newer versions like it, Whirly 01s, Millab E01 and Nutti OX. I don't if any other brand does this. I got issues with my hands (ligament surgery on left wrist and probably mild carpal tunnel on right hand) so hand grinders are usable but just a pain.

Just change the 1z for the timemore electric. Nobody likes manually grinding coffee firsr thing in the morning

I know it's months later and you probably already figure out the best grinder for your needs, but I have to mention for future buyers needing advice, that everyone here replying totally ignored your question which specifically asked for the best grinder for dark roast. Ode 2, the electrical Timemore, ZP6, etc are not good, they're light roast dedicated and they excel at that. That being said, why do you want anything other than your Encore for dark roast? You're not getting good results? The Encore is excellent for your needs, the more expensive ones are dedicated for light roasts and for one, they will result in a bad tasting dark roast, and second, they will get issues line clogging and require high maintenance with dark roast beans. The only thing I would get to complement the Encore would be a manual grinder for portability and variety, you would do good with a 1Zpresso J Ultra or Timemore C3
