I've had my Niche Zero for a couple of months now and am absolutely delighted with it. On buying my NZ as a result of DaveC's review, I also splashed out and bought the Acaia Lunar to replace my battery hungry Brewista. What a difference, the quality of my shots and therefore my lattes has improved markedly giving richer and tastier results. I've read that going from flat burrs to conical burrs can make a difference but I didn't expect it to be so dramatically better, which it is. My workflow hasn't changed much as I always weighed beans and grinds and then shot output as well. It's such a delight to get out almost the same weight in grinds as the weight of beans put into the NZ, with on demand it was never close and therefore I felt that I had no control over that variable in my process, I do now! The Acaia Lunar is a delight compared to the Brewista which would gobble up a pair of AAA alkaline within 5 days, it was the same with the replacement as well. My solution was to leave the battery compartment open on only insert the batteries when needed, taking them out immediately after. The result being that the batteries lasted approx 3 months before needing replacement. None of that with the Lunar. It's also possible to turn off some options in the settings allowing me to use only the droplet mode, which starts the timer when it detects flow and turns it off when it stops. I found the auto reset to be a nuisance so turned it off in the settings, now the time and weight remain displayed until I'm ready to change them.
