I would like to start a thread for the owners of this grinder. My guess is there is not that too many of us. I moved from Lagom P64 and playing with it for 3-4 days.

Things I like:

- speed, yeah this one is fast
- grind quality. So far not that much testing but what I see at the moment I like. Super fluffy if you not going super fine, taste-wise nothing off SO FAR
- looks: not small, but not super huge especially if you take a small hopper
- precision of GBW: it is on spot so far (up to 0.1, 0.2-gram variance but 8-10 times on spot)
- build quality: robust, serious commercial grinder
- adjustable spout, adjustable portafilter holder
- menu: user friendly
- portafilter detection is a great feature if you are not changing too many baskets
- pretty tidy so far, not a messy grinder
- so far no RDT needed (although even if you want it you can not do it :)
- "lazy shots" no wdt no tapping nothing (grind automatically 18gr, OCD tool, tamp) are very acceptable, though not very reccomended


Things that are not necessarily bad, but just come as a grinder feature being a dedicated cafe and not a home grinder:

- you are using a hopper from now on, deal with it. The grinder turns off if you take the hopper off. Could be avoided by some gymnastics but not designed that way
- I would like that adjustable filter can go low enough so I can use a portafilter dosing funnel
- you will have to open that grinder and adjust zero points and calibrate the disc distance detection system - a 10-minute job. After a month probably will have to do it one more time due to burr seasoning.
- probably not the easiest grinder to clean but depends of to what you are comparing it to of course
- it takes time to get used to the grind setting change system. I would like it feels more like stepless, it is rather weird to turn the disc I do not know maybe it is me
- retention: My guess is around 2-3 gram retention, you WILL be using more coffee than single dosing
- do not forget this is an espresso grinder, no coarse grinding

That is that so far!

You forgot to mention the digital display that shows you the gap distance between burrs, to 2 microns (0.002 mm). It shows you the internal temperature of the burrs too.
And forget what you see in the online videos of people doing reviews, and make sure to activate the burrs as you adjust finer like it says to in the manual. Keeps the burrs parallel without putting stress on them.
After I did a lot of research I went the next level with the E80 Supreme, 80mm burrs instead of 65. No grind by weight, I can live with that, just bought Acacia Lunar scales should arrive tomorrow. I bought the mini hopper too, handy as I can see whether there is enough beans in there for another shot.
Very powerful, fast, consistent, everything I could have wanted. The minimal retention that it has is quick and easy to deal with - certainly less retention than the Compak E10 that I previously had.
Early days, but loving it so far.

What made you move away from a Lagom P64 towards a GBW grinder? Quality wise (both build quality and grind quality) it seems like a side-step. Did you not like the workflow of a single doser? Or was there anything in particular that you didn't like about the Lagom P64?

I'm asking because I'm interested in buying a Lagom P64. Quite happy with my Mignon XL so far, but suffering from upgraderitus. Hoping to gain a better grind quality (finer grinds, more precise adjustment, less retention/old beans) and overall nicer looking machine that can last ages.

Thank you for sharing your experiences with this grinder! I have one on order, and I'm anxiously awaiting its arrival! (No real idea of when I might get it, unfortunately, as it appears that only small numbers of them have made it to the US recently.)

I returned my P64 to the factory because it was faulty, added money to the distributor to get GBW. Loved some/most parts of it but at the and I just like to change my beans too much so I replaced it with a single-dose grinder. I went for P100 lagom so now I am waiting for delivery next week I hope so...

I just received my GBW a couple of weeks ago, and so far, I love it. Instead of setting the DDD to zero when the grind adjustment is zero, I zeroed it on my default grind setting for my normal beans (I rarely change beans). So now the DDD reads 0.000mm > 0.007mm So why is the >0.007 mm there? I called Mahlkonig USA and they didn't have an explanation. I have to move it quite away to coarser to get rid of the 0.007mm.
