I have used a blade grinder, the Hario Skerton hand grinder (cursed - avoid at all costs), the Knock Feld2 (quite good at the time it came out but beaten by less expensive alternatives now), the Helor 101 (same comment as Feld2), the electric Fellow Opus (quite good for the price but not perfect) and the Fellow Ode Gen 2.
I use the Fellow Opus at the office with a Clever Dripper immersion brewer and it is very good for that purpose. It was not so great for the V60 at home because it produces a fair amount of fines. It was ok for the V60 but the Fellow Ode Gen 2 is fantastic in comparison when used with the V60. The Ode Gen 2 produces very few fines and an incredibly consistent grind. I was frankly blown away by the improvement from the Opus to the Ode Gen 2 on the V60. The Opus is also a very visible step up from the Feld2 and Helor 101 when used with the Clever Dripper.
For drip coffee I cannot over recommend the Fellow Ode Gen 2. It is a great grinder and well worth the price.
One big negative, is that it won’t do espresso grind.
I would happily consider the Fellow Opus as a well priced all around choice for espresso, moka pot, and drip.
I love my Clever Dripper immersion brewer. Great device for the money.
