[Q]: Makes great coffee for about 4 months. Cheaply made product. All pipes inside are cheap plastic. Even a $25 Mr Coffee has copper water pipes in it to carry the 190 degree water but not Keurig....all plastic water lines. Heat plugs the lines up in 3 to 4 months. Piece of cheap junk made to look pretty. Save your money
[A]: Negative


[Q]: A watered down perversion of the acai berry.  This juice comes on strong and harsh.  With tart aftertaste and no texture.  That's because it is mostly apple juice, grape juice, pomegranate juice, blackberry juice, blueberry juice, and tart cherry juice.  Oh yeah there is some acai berry juice mixed into this concoction.  You shall not find that distinctive  smooth chocolaty acai flavor here.  There is no milky mouth pleasing texture neither.  For that exotic unique acai experience try Zola or Samzon  brands.  I'm not saying that this Lakewood juice product isn't nutritious.  That's not my point.  I'm saying that it's a juice blend that does not taste anything like the real acai juice.
[A]: Negative


[Q]: For 100 calories a bag, these are the closest thing you will get to regular potato chips, they have great crunch and flavor.
