I own a Macap M4D and I love its consistency and program ability but I need to upgrade my other grinder and for variety reasons I'd like something different but it must have timed doses. No need for leveling and other techniques. Anyway is the timing on the Q50P accurate and consistent. Am I better going for the Q50E. Is there a difference in grind consistency? What about speed? On the M4D I can grind about 15gms in under 8 seconds. Are they as fast as this?
