Limited Capacity

In comparison to electric grinders, the Comandante C40 ‘s bean hopper typically holds fewer beans. This implies that if you grind more coffee, you might need to refill the hopper more frequently.

Depending on the user’s hand motion and power, the grinding speed can change. If you are new to manual grinding, this could lead to some fluctuation in the grind consistency.

Comandante C40 MK3 vs MK4

Comandante C40

The Comandante C40 is a manual coffee grinder that has two versions: the MK3 and the MK4. I own the MK3. Here’s a summary of the differences between the two versions:

Design: The MK4 features a slightly updated design compared to the MK3. It has a more refined and streamlined appearance.

Grind Adjustment: The MK4 introduces a new grind adjustment mechanism called “Red Clix” that allows for more precise and repeatable grind size settings. The MK3 uses a stepped grind adjustment system.

Materials: Both versions have similar high-quality construction, with stainless steel burrs. However, the MK4 uses an upgraded axle and ball bearings, which are said to improve stability and durability.

Price: Due to the improvements and updates in design and functionality, the MK4 is usually priced slightly higher than the MK3.

Overall, the MK4 offers some enhancements over the MK3, with the most notable being the Red Clix. But the MK3 still remains the best buy reliable and capable manual coffee grinder.

Alternatives to the Comandante C40 MK3 Grinder

If you’re like me and want to compare the finer details, I’ve included a few other grinders that compete with Comandante. These are generally the go-to best grinders outside of the C40 MK3, so I’ve also added why I think they could be considered superior or inferior than the Comandante C40 MK3. Just depends on what’s most important to ya!

Comandante C40 MK4

ir?t=coffeehex 20&language=en US&l=li3&o=1&a=B0B31FMPHN

I guess it’s clear by now I am a big fan of the Comandante C40, so the MK4 is my first recommendation if you just don’t like the stepped MK3 grind size adjustment and have some extra cash to spare.

  • Superior: Grind adjustment
  • Inferior: More expensive

TIMEMORE Chestnut C2 Manual Coffee Grinder

q? encoding=UTF8&ASIN=B0833SDN8M&Format= SL250 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=coffeehex 20&language=en US
ir?t=coffeehex 20&language=en US&l=li3&o=1&a=B0833SDN8M

The Timemore C2 is a great grinder. The Comandante C40 MK3 rocks a stainless steel body and stepped grind adjustment, so you can easily choose your grind size. Meanwhile, the Timemore C2’s aluminum alloy body is lighter with a stepless grind adjustment, and it’s super portable. Plus, the Timemore C2 won’t break the bank.

But it’s just not in the same league as the Comandante C40 in my opinion. Ultimately, your choice depends on what you’re after—personal preferences, budget, and specific needs.

  • Superior: Cost. The Timemore is way cheaper than the Comandante C40.
  • Inferior: Construction quality and performance.

1Zpresso JX-Pro S Manual Coffee Grinder

q? encoding=UTF8&ASIN=B0BJZZ51GY&Format= SL250 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=coffeehex 20&language=en US
ir?t=coffeehex 20&language=en US&l=li3&o=1&a=B0BJZZ51GY

The 1Zpresso JX-Pro is a veritable legend in the coffee sphere because it’s so excellent to travel with. Its grind consistency, smooth operation, and precise adjustments are all equally as top-notch. And it’s cheaper than the Comandante C40 MK3.

But from my experience, the latter grinds coffee more consistently, so you get a uniform grind size for better flavor. It also has low grind retention, meaning you get fresh grounds every time.

  • Superior: Cost. It’s more than the Timemore, but still below the Comandante C40’s price point.
  • Inferior: Durability, consistency, and grind retention.

Our Verdict

I am thrilled to share my experience and offer a thorough evaluation as a proud owner of this great item.

In conclusion, the Comandante C40 grinder is unquestionably a high-end item, and its effectiveness justifies the cost. The grind quality and durability of this grinder are amazing. I fully recommend it!
