The only good thing about this compact burr grinder is it is lightweight.
The problems with this grinder are a lot and nothing good for it.
All plastic including the burrs
so small will not fill enough for a poor over
Grind so inconsistent
Will not work with all beans
Let us go into each
1.
Grinding Peaberry, light roast, And some medium roast Make this Grinder impossible along with The hard and dense beans Already breaking the grinder's burrs. I What's only able to use this one time before it was broken.
2.
The grinder size for the amount of coffee to be able to be used is less than one Pour over, The grinder can hold roughly around 14 g of coffee depending on the Varietal, roast, And freshness.
3.
Like most handheld grinders this one has no difference, by turning The adjustment on the bottom to the desired grind size. The problem with this one is by turning it still stays inconsistent much like using a blade grinder and trying to do fine-grained like espresso is impossible. The only way to do a good grind on This grinder is to buy using a coarse grind which is not the I Ideal setting for making most poorovers.
4.
As mentioned above With grind inconsistency, this coffee grinder will not work with all coffee Beens. I tried this with light, medium, and dark beans from different regions. I found that coffee from Hawaii, Ethiopia, and Columbia being somewhat denser as light or light-medium roast has more problems than a full city or an espresso roasted coffee along with finding peaberry is been the most difficult along with Maragogipe. also depends on the type of processing the coffee has been through before grinding in that naturals and honey had more problems then wet.
