Both cups seem to provide a good cup of coffee thru the KEURIG K-2 machine however the SOLOFILL K-3 cup did not allow any grounds as the ECOBREW did, the fines were about the same, but the flavor that came through the SOLOFILL cup brew was better, a positive point!I'm not sure what Amazon or SOLOBREW is going to do to try to change this issue, but something has to change

This is perfect for people like me who want freshly ground flavor but just one cup in the morning is plenty (actually, it's great for more than that too because you can grind as much as you want at the grind setting you like).

Yes, the grind consistency is not uniform, but, I don't care about the technicality - the flavor is much better than the consistent blade grinder

Please don't buy this grinder if you like the flavor of

Really loved how this grinder worked and the improved coffee flavor.

The coffee grounds stick in the chute and if you don't tap the sides to get those to fall into the cup, they will fall down when you bump or have to move the grinder later and it will be a pretty good sized mess.4

I can't use the Carafe sized cups, nor the Keurig brand refillable for the 2.0.It's now pretty much sitting on the shelf unused, until they make an insert to support larger sizes of containers -- like for the carafe.

You HAVE to tap the sides of the grinder before removing the reusable k-cup or there will be a time when you do have a pretty good sized mess

Its small size is convenient on my countertop, so I'm keeping i.

It does not spill grind, and it fills the pod perfectly with your preferred size granules

I wish it would have worked because it is such a great idea.

Great idea, did not work.

Great idea but VERY messy and only lasted for about 6 grind cycles

This product is a great idea, but this particular device does not work as advertised

Much, much less expensive + better tasting, fresher coffee + essentially zero waste

If you are using a good bean the coffee taste wonderful and a pound of beans from Starbucks is lasting me at least 4 times as long (so far, its not gone yet) as the box of K-Cups they sell and the beans are only 2$ more

Easy to use, grinds exactly one cup’s worth of beans at a time, and fresher coffee tastes great!

I changed the grinder between A to B with better taste but the problem to close the filter remains

Hoping this will also get me a better tasting cup of coffee out of my keurig.

Love love love this item

I think this is a fantastic item, I agree that a setting of B and a time of 3 is perfect for the cup that comes with the grinder

I love this item as it should fill a niche that has not other competitors (at least at time of purchase).

LOVE this item

Highly recommend this item!

If you DON'T do this, you can count on that stuff dropping out randomly, likely when you don't have a pod in it to catch the grounds, and it's a waste as well as a mess when it does.

1. does not grind for coffee -- makes coffee bean pieces all over my counter.2.

This machine just does not grind coffee fine enough for k-cups and overflows all the time

Just have to remember to clean it out - the coffee does get caught up in the machine alot

This machine just does not grind coffee fine enough for k-cups and overflows all the time

When I tried the one that came with the grinder, my Keurig 2 machine rejected it.

TERRIBLE MACHINE

The machine itself is good but the KCUP ISNT.. bought this machine specifically so once its filled or finished grinding

I'm not saying its a terrible product but be prepared for clean up after grinding.

Awesome product, but it clogs a lot and the external portion needs to be cleaned after almost every use

This is a great product - why pay for K cups, if you can grind tour own FRESH coffee when you need it, one cup at a time

This product is a great idea, but this particular device does not work as advertised

And to top it all off, I drank watered down coffee because I wanted to like this product

You also have to use ground coffee which never is as fresh as grinding each cup

For a solofill to work good, coffee has to be ground to a fine, espresso grind

I also use this when making espresso; I set the grind to A and timer to 3, fill the V1 basket and then dump the grinds from the V1 basket into the espresso filter basket; that's also pretty much hassle free

Because of its violent, not so fine grind, it vibrates and moves all over the counter

It does produce the perfect grind for a good cup of coffee.

The only thing missing from a perfect cup of coffee from my keurig was fresh ground beans

Placed cup in Keurig machine and out came a perfect cup of coffee.

K-3 Chrome filter fit in the adapter as well as the SOLOGRIND settings were where as suggested I proceeded to grind my first cup of coffee beans

Great grind, just the right amount of coffee, and a perfect cup, every single time

You can also grind multiple cups at once by changing the container if you have a regular drip coffee pot

In this role the grinder work just fine...until it didn't

Please don't buy this grinder if you like the flavor of

This grinder gave the same overfilled grind no matter how the front or rear dials were set

And this grinder works surprisingly well for a first gen product.

And this grinder works surprisingly well for a first gen product.

This was one of the cheapest ones available and it has worked very well.

It has worked great for a couple months now, and I'm really happy with it.

This is perfect for the single-serve coffee makers if you don't want to buy the pre filled (and expensive K cups).

This grinder works well, the only problem is the setting dial for the amount of beans to grind

I really like the ease of my Keurig, but I *hated* using the non-recyclable, expensive k-cups

The cup is perfectly filled with the correct amount of ground coffee!

The idea here is perfect, grind the perfect amount, for easy, no mess coffee

This works well if you want fresh coffee for your Keurig

I also have ground coffee for others brewing coffee makers.

I was searching for a coffee grinder that could grind coffee fine enough.

The machine, not heavy enough nor the rubber feet have enough friction, rattles and spins around while grinding.- With French Roast, rich and oily, the small square channel between the grinder and container gets frequently

When I grind dark-roast Peet's beans, I have to clean out the ground coffee shoot regularly because the extra surface oils on dark roasts stick together and clog the chute

Also - if fresh (roasted 1-3 weeks...no longer

While this works, it sure would be nice if the machine worked as it's supposed to.

That's a solid A in my book

The directions could be clearer but it is worth the money if you want to grind your own fresh coffee beans.

I then tride to grind some more beans and transfer them by hand.

The only thing missing from a perfect cup of coffee from my keurig was fresh ground beans

Just fill the hopper with your favorite coffee beans, insert the Solofill cup (also highly recommended) into the machine and press the button.

Also learned the hard way to pop a fresh cup into the grinder right away

Best way to get around the overfill issue is to fill the cup up with whole beans and only grind that amount, because the "timing" function grinds too long

It seems that would be either way too much coffee for four cups or not enough for ten cups

It didn't quite work out the way I wanted, but in the end, it actually did work out

The grind is way to course even on the finest setting and it overfills the coffee maker cup that came with the machine even on setting 1

the dials of grind size and time seem to be cosmetic.7.

Great grind, just the right amount of coffee, and a perfect cup, every single time

there were no grinding mess out of the back of the machine the second time

Especially that depending on the bean different grind setting and time may be required.

Great grind, just the right amount of coffee, and a perfect cup, every single time

If it grinds for 11 seconds for one cup then it should grind 44 seconds for four cups and 110 seconds for ten cups using the one cup setting as a guide - which can't be right

I have a Keurig K-Supreme Plus C and the My K-Cup Universal Reusable

Working the other way - if it grinds 20 seconds for ten

then it should grind 8 seconds for four cups and only 2 seconds for one cup - which seems more logical and would eliminate the K3 adapter from being overfilled but they didn't program it that way.

Tends to fill solofil cup a bit too much, but I just keep a pretty bowl nearby to tap it down and dump a bit of excess grounds into

I find that anything under a "B" grind (more fine) tends to have too much residue in the coffee and anything greater than "C" (more coarse) doesn't have as much flavor

There is always a little bit of grindings on the counter, but no problem to wipe up

We have been using our 10+ year old Braun grinder, which still works fine, but it is a bit messy, and transferring the coffee to the K-cups is also a bit messy.
