Save your money and do not buy this product. Does not even come close to bacon flavor more like a hickory smoke taste. After everyone in my family tried it we all agreed it was nasty(we're not picky either).

I purchased this item as an alternative to traditional K-cups in an attempt to save money; however, this product did not work well in my machine. I followed the directions and read reviews to see what works best, but was not able to use the K-cups effectively. The cup itself is too weak and warps in my machine. I compared the shape before and after and there is a big difference; this K-cup seems to expand horizontally and vertically because the plastic is not strong enough. Also, the K-cup is shaped differently from the traditional K-cup. This is neccessary because it does not use foil as a topper, but does not seem to work. In the end, I had to clean up several coffee explosions in my kitchen to figure out how it works, but still could not use it effectively. Maybe I am not doing something correctly, but I'm sure there is also an issue with the product itself. While I do like the idea, I would not suggest purchasing this product until the bugs are worked out.

This product is absolutely not to my taste.  It is advertised as a carbonated juice drink, so I kinda expected something along the lines of Welch's Sparkling Grape Juice; I was wrong. The first thing I noticed after opening the can was the aroma; it was unpleasant.  The drink is not very strongly carbonated and there isn't much bite to it.  The strawberry/kiwi flavor is very muted and is masked by something terrible.  The taste was bad going down but worse after a minute or so, as the aftertaste is strong and unpleasant.  On top of the bad taste and unpleasant aroma, the drink has a considerable amount of calories for a small can at 135 calories per 8.3 ounces.  Perhaps there are vitamins and things in the drink that make it worthwhile for people who... well, I am not sure who might like this stuff.  1/5 - not recommended  Your mileage may vary, but I just don't like it.
