Heavily touted by the reviews, decided to try.  Mix is good, but not great.  Probably wouldn't buy again.

I have never taken the time to write a review before, but in this case others need to be warned off. I expected to get a product similar to what I have seen in the stores, but this obviously is a replica. The sliders on the bottom of the tray that are supposed to keep the tray straight when you slide it in and out broke off before I even got it out of the package. It is not something you can fix unless you have a solder gun. Even then, it is very "sticky" pulling the tray out because there are no rollers. It is metal on metal, which does not work well without some sort of lubrication. I love Amazon, but this product is inferior at best.

I was anxious to try these cups since they seemed to be sealed like the original K-Cups, but was very disappointed in the product.  Though the cups came with no instructions, it was apparent that you just put the filter in, add coffee, then pop the lid on.  Trouble is, the filters size and shape indicate they should hang over the outside edge of the cup, but when doing that I found it impossible to seal the cups.  So I had to tuck the filter inside to be able to close and seal the lid.  After doing that and trying, the coffee ran VERY slow though the K-Cup and after only about three cups, the Keurig machine seemed to get clogged up and stop working.  I cleaned out with vinegar and tried again, but same result.  I ended up throwing these away as it didn't seem worth the effort to return them.  NOT a good product!
