Noel, Until I read your post I only cleaned the chute and doser between sessions. So, this morning I removed the hopper and inspected the freed hole with the burrs to be seen. I saw surprising few grounds. After vacuum cleaning the hole all visible grounds were gone. Of course, I need to screw off the top of the K10 for a 100% inspection and plan to do that in a couple of weeks. So far, I am still very happy with the K10. Does this answer your question?

Wilco, thanks for the info. Yes, it does answer my question. K10 Compak sounds to be a nice grinder. Tempted to sell the M5 and purchase a K10. A few months of side by side comparison with the MX. Then keep the grinder I like the best.

New on the horizon: "Introducing the Compak K11...even louder than the K10."
For those with a "what the" look on their face, it's a reference to "This is Spinal Tap"

Rob, Your post did not pass the language barrier. Can you explain?

Obviously, you've never seen the movie This is Spinal Tap . . .

Nigel Tufnel: The numbers all go to eleven. Look, right across the board, eleven, eleven, eleven and...
Marty DiBergi: Oh, I see. And most amps go up to ten?
Nigel Tufnel: Exactly.
Marty DiBergi: Does that mean it's louder? Is it any louder?
Nigel Tufnel: Well, it's one louder, isn't it? It's not ten. You see, most blokes, you know, will be playing at ten. You're on ten here, all the way up, all the way up, all the way up, you're on ten on your guitar. Where can you go from there? Where?
Marty DiBergi: I don't know.
Nigel Tufnel: Nowhere. Exactly. What we do is, if we need that extra push over the cliff, you know what we do?
Marty DiBergi: Put it up to eleven.
Nigel Tufnel: Eleven. Exactly. One louder.
Marty DiBergi: Why don't you just make ten louder and make ten be the top number and make that a little louder?
Nigel Tufnel: [pause] These go to eleven.

Thank you for the link Jason. Indeed, I never saw this movie. The only braincell I have left nearly went up in smoke by trying to understand the conversation you showed between Nigel Tufnel and Marty DiBergi. I am glad American movies are subtitled in Holland.
Honestly, I thought Rob did try to let me know he is a dog lover. I thought, perhaps he suggested K9 to be a dog, K10 obviously the well known grinder and K11 a K10 grinder that is vacuum cleaned and therefore making the sound of a K9, a barking dog. Which I associated with Frank Zappa ... but why? And then I felt sorry for Rob. Obviously, his vacuum cleaner is out of tune and he does not know. Anyway, vacuum cleaners in Holland generally make a more or less civilized sound, maybe because of the 230 V.
And now - thanks to you, Jason - I know he meant something else. Although I still don't have a clue what that can be. Perhaps you have to be an American to understand or perhaps I need to updose my espressos or maybe the development of my humor stopped before 1984. And now I am feeling sad.

Jason, thanks for trying ;>D
Wilco, sorry for your consternation. It was a play on words, having to do (as the movie dialogue portrays) that a K10 is great, a K11 is greater...or something like that.
Please ignore any of my future posts
Merry Christmas.

Rob, I appreciated it.

Wilco, sorry I dragged your thread temporarily OT.
Back OT. Is the new doser lid easier to handle then the one that looked as if it was one giant piece of connected to the entire grinder?
Also, does it have the extra "start up" motor(or whatever it is that facilitates a quiet start) that the Mazzer's have?
See, back OT..sort of.

Reading Rob's posts I sensed a certain unfulfillment, a secret wish to reach a higher level of happiness and satisfaction. How can I help such a nice guy? Therefore I asked Simon to study his posts. Simon is not only a friend of mine, he is also a trained anthropologist and a certified psycho analyst. Further, on a regular basis, the Amsterdam Police Force asks him to act as a profiler in their more complex serial killer cases.

Simon: "This home-barista website is very interesting. I have not seen such a wide variation of psychological profiles centered in one place in a long time. Here is an enormous amount of extraordinary material to study. I have to thank you for bringing this website under my attention."
Wilco: "Please, can we focus on Rob?"
Simon: "Sorry. Well, Rob's case is particularly interesting. Of course, my opinion can only be preliminary as I have not interviewed Rob as yet. That being out of the way, I can tell you Rob does not have much excitement in his marital life anymore."
Wilco: "Wow, how do you came to that conclusion?"
Simon: "You mean, apart from he says so himself in this thread? Well I observed that he seems to spends almost his complete time, night and day, behind his computer and posts on all threads, alive or not. He is a very productive contributor on this website. Which make me wonder who is responsible for scraping together the daily household income. I presume that will be his wife. If true, this explains the lack of marital excitement. This posting affair is really like a drug addiction."
Wilco: "I see. Can this addiction be treated?"
Simon: "Yes, there are different strategies possible, ranging from hypnosis to electro-shock therapy. Only, most of these strategies don't have a lasting effect. Perhaps, we can do something different now. Your hunch that Rob is a dog lover is correct, I think. It is a pity he does not know that himself. So my advice is, he should buy a dog. The dog could play the role of mediator between Rob and his wife. If Rob sees his wife cuddling with the family dog, he possibly wants to do the same. And after some time, when his wife sees Rob cuddling with the dog, she wants to be cuddled too. After some more time - these things can take ages in my experience - all three are cuddling each other as one big united family.
Wilco: "Sounds like a novel idea. Any suggestions about the type of dog?"
Simon: "Let me think. Important is that the dog is nice to touch. Perhaps a bold one, like the original Chihuahua. If his wife like to play with hair, Rob could also think about a French poodle. Potential problem with poodles is they are sometimes too intelligent for their owners. But - having seen his writing - in this case, I think a poodle can fit. Later on, when his wife is used to lay and play around with a small dog and her revived husband, he could expand his family with a Great Dane. That truly will excite such a household."
Wilco: "Wonderful advice! You must be an expert!"
Simon: "Don't mention it. It is indeed a wonder that I am still such a humble man. On the other hand, you seems to be an expert yourself too. This espresso tastes absolutely fantastic. And what a beautiful grinder do you have. May I touch it?"
Wilco: "It is her, not it. And if you touch her, I will kill you!"
Simon: "Oh my, sorry, no offense meant. But if I may speak freely, I admire her beautiful low pitch grinding sound. She must have a big motor, does not she? With also a start motor to help her to be on rev immediately after switching her on, right?"
Wilco: "That is correct. And her lid is just as easy to remove as with my boxed up Mazzer Mini. Yes, I love K10 .... and my wife of course."
Simon: "Hmmm, you were just in time. Are you interested in a private session?"
