Very good grinder! It takes a little trial and error to find the right setting to grind the desired size of the bean, but afterwards it is very good! And you can also do your morning workout while grinding and smell the freshly ground coffee!!

It does not produce "powder" no matter how much you tighten it, so it is not suitable for Greek coffee. The handle changes securely. The silicone wheel changes with another thinner one for a higher cut.

It is quite difficult to adjust, after 1 month of having it and still haven't found the right size.

I have had it for quite some time, about 8 months. I use it every day for Aeropress and French press. One downside is that the top screw comes loose as you grind, so the stone starts moving from side to side. It needs to be tightened 4-5 times to grind 15 grams of coffee. I think it grinds correctly and evenly. Depending on how fine you grind, it takes different amounts of time. For example, to grind at setting 4 (the finer the grind, the lower the number), it takes about 2 minutes. Ergonomically, it is not convenient because it has a large diameter to hold with one hand, and it is not at all convenient to hold it down and rotate with the other hand. One last thing I want to note is that a glass flake came off in the jar's thread, without me realizing that I hit it so hard. I reserve judgment for a negative rating as it is my first grinder and I have no point of comparison.
