This is my first power grinder. I have arthritis in my hands and hand grinding is painful. I purchased this grinder (after watching many videos) because it appeared to be one, without breaking the bank, that could grind Turkish-style coffee. It grinds very fine when set up properly. <1 on the dial. Overall I am pleased with its performance so far. I also drink filtered coffee along with my wife but prefer Turkish.

I've had the SD40 for about a month. Overall, I'm happy with it but think that there could be some improvements. Out of the box, I love the size and the weight. Very sturdy construction. After dialing it in, I found the grind quality to be excellent, but calling it "low retention" is a bit of a stretch, IMO. If not for the bellows it would retain quite a bit of coffee. Things I think could be improved: 1) Increase the size of the bellows. Add one more "pleat" so that more air can be forced through per push. Right now it takes too many pushes to remove all of the ground coffee. 2) Shorten the "fingers" on the anti-clumping gasket. They really don't do much to reduce clumping and just get in the way. 3) I wasn't happy with the large amount of change between clicks on grind adjustment ring (approx. 4 marks per click). I did some searching and found a mod online that allows the ring to stop at every mark on the dial. I 3D printed it and it works great. I now have 105 stops as opposed to the factory 36. Not "stepless" but close to it. I sold a Niche Zero for this grinder and have no regrets. If Turin would make a couple of changes (especially the bellows and the adjustment ring) they could turn a very good grinder into a great one.

Preordered this because we have replaced our Breville Espresso machine with the built in grinder with a Rocket espresso machine. Pros Very lightweight Grinds for espresso really fast Low Retention Very quiet Cons The magnetic cup doesn't sit still it sometimes moves in a circular motion. Always powered on which is ok but the placement of the button to start the grind is at a place where it can be pushed by accident. The power button seems a bit flimsy sometimes I have to push it twice to start/stop the grind. I've had this for about 2 weeks now and so far I like it. I've been trying to find more videos on it to teach me some tricks and tips to use it better for my espresso shots.
