I received one of these as part of my purchase on a Sage promotion. Rather than woffle on about it this is a link to it for sale on Amazon

I did use one a few years ago and as an entry level grinder they are ok. Nice display, adjustment dial has an electronic display. I did single dose with mine and obviously it is not designed for that but again it depends on your needs. I have a Niche Zero somewhere. I have found the box but not the grinder which is frustrating. I have probably lent it out! I need a second grinder purely for decaf. This Sage would do for that I guess but as I say, I know I have a Zero! They come with 54 and 58mm pf forks that take 0.4 seconds to swop over.
The grinders are circa £200. I want £100 for it. I have not even connected the hopper so it is unused. I am happy to courier at your risk and expense. I do not have any packaging as it came with the Dual Boiler but I am still able to package it up well. Or you can collect from NE23
