I think this grinder is good value for money - a really good entry into better coffee grinding. It is loud, but this is known already. The grind is very uniform to my untrained eye and comes out clump free from the chamber. Grinds 20 grams in around 6.5-6.8 seconds at my grind size. Set dosing amounts via timer is really accurate and I find this a great feature of the grinder. I generally grind 19 grams then settle the grinds and add a short burst for the last gram, works very well. I did have to add one of the shims after about a month as I was finding the grind not small enough for my machine (breville dual boiler). All in all a great little machine for home use, with only one down side (the noise).
