Hey guys, whats your take on this statement, I got it from the Macap Stepless M-4 write-up on Amazon:

This grinder is prefect for any dedicated espresso set up but is not recommended for situations requiring grinding for various methods of coffee brewing as the grind adjustment happens very slowly.

I will be using this for coffee until the spring when I splurge on an espresso maker in the $1500-2000 range. I will probably make it on the stove to practice and get familiar, but will be using the grinder for day-to-day coffee until I pull the trigger.

Why would that be the case, and thank you for teaching me the art of coffee.
