loud as all heck but that is their nature. The delivery nozzle is coated in a rubbery plastic and builds up a lot of static this make the finer coffee grinds cling to the nozzle. There is always old grinds left in the mechanism and the dryer ones that have clung to the nozzle so this needs constant cleaning to avoid contamination of older grinds.

Giving the grinder just one star for the moment,I have only had it about 30 hours and have been at work most of those so not much chance to try it outNot happy that it came with euro plug so had to source an adapterIn some reviews people are getting an espresso grind On a high setting,but I started on 20 and went down to 5 which was not fine enough as coffe came through too fast and at 0 coffee would not come through, then on 2 it just about came through so I don’t have many options left.My machine is the sage duo temp pro and I am using fresh beans with a good roast date but am struggling to get good tasting shot, not bad with milk but awful black so don’t know if it’s the machine,grinder or me.Need to do more tests before giving a proper review....costing me a fortune in coffee this dialling in, now on my second grinder first one cheapWhich I hacked to give finer grind which wasn’t good enough.if anyone out there has any helpful advice would be very welcome.
