Very convenient to use, easy to change grind size.
May also be used together with the Hario Smart G Electric Grinder.

This is so handy so that I can bring it along with me when I travel.

Basic grinder good for coarse grounds for pour over coffee. Not for espresso or fine grinds.

I saw this grinder on one of James Hoffmann's YT video and thought why not give it a try, it's a nice grinder easy to use and carry on, definitely an affordable way to entry to the world of making your own coffee (≧∇≦)b

Compact and yet good for 1 to almost 4 cups of coffee. Because it's small, it's easy to clean. Ergonomically, easy grind. The trick to getting the correct configuration is to tighten the mechanism to the limit (turning clockwise) and then count the number of clicks as you turn anti-clockwise - do remember to record it in your brew notebook as you experiment to get the appropriate grind. There is a video on youtube, like a video manual on the use of this grinder - it even show you how to dismantle the mechanism for a full clean. I don't really dismantle the grind to wash it, I just give it a thorough rinse each time after use.
