C40 MK4 Nitro Blade
Precise operation thanks to exceptional quality and first-class materials.
The Comandante manual grinder - Virginia Walnut.
Comandante has further improved its proven quality with the C40 Nitro Blade. With its aesthetically pleasing design composed of tasteful light wood elements, the Virginia Walnut C40 is the pinnacle of professional coffee grinders.
In a patented process, the burr of the new grinder is entirely made of stainless steel, resulting in an extremely durable blade-grade steel material. After hardening, the edges of the burrs are sharpened again, effectively "cutting" the coffee beans. Thanks to the unique grinding technique, the grinder produces an extremely precise and homogeneous grinding result with virtually no fines across all grind sizes. A double ball bearing ensures optimal power transfer with each grind, making the crank movement smooth.
The grinding mechanism:
- Extremely robust and durable
- High hardness and high toughness for high cut resistance
- Particularly uniform grinding
- Extremely sharp Z-cutting blades, individually sharpened after hardening
- Newly developed grinding geometry
- Very easy handling thanks to the grinding axis with double stainless steel ball bearing.
- Stainless steel grinding body laminated with bamboo.
- Homogeneous grinding result
- Very precise adjustment of grind size in individually lockable steps.
- High grinding speed: about 1 bean/turn
- Ability to grind or cut spices and tea
- Stainless steel handle with removable solid oak knob.
- High-nitrogen martensitic stainless steel
- Conical stainless steel grinding mechanism made according to a patented process.
The grinder:
Capacity: 40g
- Crank locking on the axis through magnetic connection
- Double encapsulated stainless steel ball bearing axis
- Removable oak wood crank handle, attached to the crank by a pressure lock
- All plastic parts in Eastman Tritan copolymer.

Koorui 34E6UC (34" 3440×1440, 180 Hz, 1000R curved VA panel) — But Missing Info Buyers Should Know
Size: 34"/WQHD/1000R/HDR400
Review:
I purchased two of the Koorui 34‑inch curved ultrawide monitors for a dual‑monitor setup, and so far I’m very pleased with them. The picture quality is sharp, the brightness is solid, and the “Normal” color preset looks natural without any adjustments. For the price, these 34‑inch panels deliver very good performance.
That said, there are a few important details the product listing and reviews don’t mention — and knowing them ahead of time would have saved me some stress during installation.
1. YES, the 34‑inch model DOES include stand‑offs (spacers)
This is not mentioned anywhere in the listing, and even Amazon’s Rufus incorrectly says they are *not* included. They actually come in the small accessory packet with the manual.
If you’re mounting these monitors, you will need those stand‑offs because of the recessed VESA pattern. They are already in the box — just not advertised. I rushed to order a separate spacer kit because the listing didn’t mention it, so I’m putting this here to help the next person avoid that.
2. One of my monitors flashed briefly until I disabled FreeSync
On one of the two monitors, I noticed a quick bright “flash” when moving the mouse. Turning off Adaptive Sync / FreeSync in the monitor’s menu fixed it instantly. The other monitor didn’t have this issue, so it seems to vary by panel.
Not a defect — just something to be aware of if you see flicker or brightness pops.
3. Color and brightness match well once set manually
After setting both monitors to the same brightness, contrast, and color mode, they match very well side‑by‑side. The “Normal” color preset looks the most accurate on these VA panels.
4. Build quality and packaging are solid
Both monitors arrived well‑protected, and the included cables work fine. The stand is basic, but I’m using monitor arms, so that wasn’t a factor for me.
5. Too early to comment on long‑term support or durability
I’ve only had these monitors set up for a few hours, so I can’t speak yet to long‑term reliability or how responsive Koorui’s support is. I’ll update this review if anything changes over time.
Bottom line:
These 34‑inch Koorui ultrawides are excellent for the price, especially for gaming or a dual‑monitor setup. Just be aware that:
- Stand‑offs ARE included (despite the listing not saying so)
- FreeSync may need to be turned off on some units
- Picture quality is great once you match settings manually
- Long‑term support is still unknown
If the listing had mentioned the included spacers, it would have saved me a last‑minute order — so I hope this review helps the next person.

Awesome monitor! (my 3 year review)
So I've owned this monitor for about 3 years now and here's what I have to say about this monitor. The picture quality is actually really good. I got the 1080p version and I mostly use it with my Xbox series x and occasionally will use it for some lighter gaming on my gaming PC both work effortlessly well. The screen size is okay I think next time if it's in the budget I'll buy there 34 inch curved monitor. But for right now I'm sticking with this monitor until it dies and so far it's running strong 3 years later. Right now this monitor cost $80 which is an absolute steal at that price. I paid $130 for it and would say it's absolutely worth getting. There's no flickering. The setup process went smoothly. It's compatible with both my console and gaming PC! I absolutely love this monitor! I don't own the 27 inch version but I'd recommend going with either that size or bigger if you can afford it.
