Half the cups are no good.  Very disappointed.

I love this product, however, halfway through the box it only makes colored water now.  After trying four K-cups I finally opened the cups to see what was going on.  All the powder had congealed into a lump.  Needless to say I'm really disappointed - I'd started depending on this as my major go-to in the evenings.  I'll have to throw half of it away.

Normally, these are great. I can use each one to make a half gallon. The last time I ordered these, I ordered 2 sets of 2 boxes. 1 entire package that contained 48 k cups was defective. The foil tops would puncture a hole that was too large and once the water ran through, it would flow back out the top and bring tons of ground up tea over the top and into the cup of tea.

While these flavors taste good (when you can get them to work!!) the cups do not work right!! Everytime I use one of these in my machine it leaks all over the place and I'm lucky if I get a 1/4 cup out of it. These are terrible. I don't know why but, I can use any other cups I have on hand before and after these and those work fine. When I go to use these. What a mess!! Don't waste your money.

I bought this 50 pack and threw almost all of them out. They are overfilled and when they get wet, grounds go in all directions. What a mess.

One order was good, second order was mis printed. 3 of the 5 cups were printed ~10ml above thr actual measurement. This affected the 50ml cup measurements the most. Good thing i caught it!  Check the measurements!

What a surprise when the 12 ounce cups arrived and are way smaller.  If you fill it to the brim you get 10 ounces but what that really means is it's an 8 ounce cup.  Either the Amazon people shipped the wrong item or the cup is simply not as advertised.

It's only $20 but I'm beginning to get mislabeled products and things like this all the time from Amazon and am starting to buy less from Amazon as a result.  It's either careless or deliberate.  Either way it isn't what I ordered and I'm unhappy.  I'd give it no stars if I could.

Garbage. Over 1/2 of the cups in the box of 100 that we bought either backed up in my brewer and made a complete mess or filled my cup with grounds. I still have 40 left but they're going in the trash where they belong. Spoke with a rep from Kraft foods and they said they cant do anything because I bought them through Amazon. Definitely won't buy anything from McDonalds again. Am hoping Amazon will stand behind this crap or I might be done with them as well.

DO NOT ORDER.  I recently received this order and the K-Cups have a defective seal that blows liquid out of the side all over my counter.  I do not have this issue with more expensive store bought K-Cups, so Amazon has obviously changed to a cheaper manufacturer to make it's prices.  Buyer be ware!

I just opened the package, which was smashed in, by the way.  Instead of the six cups shown, I received one pink cup.  The one cup is all scratched up and has something black on the lip. It's definitely been used  a lot!  Yucko!!!  The only place for this thing is the trash!!!  Definitely not worth the $1.50 and 6.99 S&H.  It's going back!!!  I might even send it back in the same smashed box it came in.

These are the worst K-Cups I have ever purchased. They allow coffee grounds to bypass the filter and clog up my machine. Over 50% of the cups were defective. I will never use this brand again. I am attaching a pic that shows the grounds at the bottom of the K-Cup when I cut it open after brewing a cup of coffee.

I ordered this item and have gone through about half of it. The problem is that I have experienced at least a dozen or so of the cups have nothing in them. The cups weren't damaged they just were manufactured without the coffee. Not easy to tell unless you really shake them to hear a noise but even that isn't always a tell tale sign. Obviously poor quality control. I won't be buying this product again.

UPDATE******  Almost done with my order of 72. 1 in 5 are either manufactured with no or a scant amount of coffee. Very poor quality control.

Some cups are 5 stars, some 1 star...average 2.5 stars. I'm averaging down to 2 stars though, versus 3 simply because of the inconsistency.
So far I have used about 11 cups of this. 6 were really good, just like you'd get at your favorite convenient store on a road trip. They don't require any 'extras' although I will add a little sweetener, but most folks don't drink coffee type drinks as sweet as I do. However, 5 of these were extremely weak, you can actually see a huge difference as it flows down to the cup. I've gone through about 8 other cups by hand, feeling, shaking, etc. It's obvious they had (hopefully past tense) a quality issue where a machine was out of calibration or something. Some cups are all but full, some seem to be 20% full, and the range varies between the two. I've had these for quite sometime now because I'm normally a plain coffee drinker, and I ordered such a large quantity of these because of a coupon and subscribe and save. However, if the first two cups had not been so good, I'd have requested a return/refund immediately. If you get a good batch, I'd recommend.

This is my favorite coffee, however this is the WORST purchase I have ever made.  More than 60% of the k-cups had defective seals.  That meant a cup full of coffee grounds as well as an awful mess to clean up in my Keurig!  I have never had this problem with this same brand purchased at the grocery store.  So, instead of saving by buying in bulk, I ended up paying close to 50% more due to the large number of unusable k-cups.  Before using, check the tops.  If they are flat and/or crumpled rather than smooth and rounded, trash them or you will have coffee grounds not only in your cup, but all over your Keurig.  I really, really hope Amazon discusses this situation with the seller to institute quality control or discontinue selling the product in bulk.

Costs more for half the coffee and isn't as good.

We have had two failures where the cups clog, pressure builds and they explode sending hot liquid all over the place, including on you. The samples were expired months ago which likely accounts for the awful taste. The products have to be ordered you can't get them locally even at Bed Bath and Beyond where they say you can get them. You can't use K-cups, which are available everywhere.
I really think the machine is very well made and could be good but having to order the products and it not being very palitable, honestly I wish I had bought a K-cup machine.

So disappointed. Nice mug but when I got them 2 of the mugs were completely shattered.

This is  advertised as a set that includes 1/6-cup, 1/4-cup, 1/3-cup, 1/2-cup and 1-cup sizes. I purchased this because I specifically wanted a 1/6 size measuring cup. This does not contain a 1/6 size. I contacted amazon and they told me to keep it and issued me a refund. They said they would change the description but as of 9/22/2014 it still says 1/6 cup. So beware. Also, I have now used these a few times, and I suppose I should not complain because they were free--but the quality is poor. The handles are quite flimsy. My 1 cup side handle bent when I was measuring cups of flour. So I am going to end up donation these to the kids to use in their dirt pile.
