Timemore Slim Grinder Black Diamond PLUS - black

Have a nice day Honzo :). You have definitely chosen grinders that I myself would recommend to you if you grind especially for filter coffee. Both are really great grinders, both in the resulting consistent grinding, and they are both reasonably priced for what they can do :).
The internal structure of the grinder is very similar as a result, both have 38 mm stainless steel conical stones, double holding of the main axis, coarseness adjustment at the bottom of the grinder and both are screwed together. The only thing is that Timemore has newly developed grinding stones that can consistently grind both filter and espresso (maybe it would be useful for you in the future). The volume is also quite crucial. The Q2 has a slightly smaller bean container than the Timemore, which is not suitable if you plan to make, for example, the Cold Brew in large quantities. But it depends, of course, on the size of the grains themselves, which you will be grinding :).
I have personal experience with the Timemore grinder (C2 Nutty) and I have been very satisfied with it for a year and a half, it grinds beautifully consistently, quickly and the surface of the grinder, which Slim Plus also has, is very pleasant to hold when grinding :). So in the end, as you write, the main point in the decision will probably be the design and which brand is more pleasant for you :). Best regards, Hanka
