[Q]: I have older mats that have a ribbed surface and work great. These have small stiff points and actually hurt to lean on or kneel on. I can imagine that they hurt my cats paws ad that is why they tend to jump over them when exiting the littler box.
[A]: Negative


[Q]: While I typically like the Happy baby products, I was very disappointed with this product. Unfortunately when I opened the first of six containers it smelled stale as if it had been sitting on the shelf for a very long time. I decided to mix up a bowl but after tasting a bite, it confirmed my initial thought--it was old despite the expiration date. My guess is that I received a bum batch however, I am not willing to try it again when there are other organic cereals I have been happy with.  I will say I was extremely pleased with Amazon's customer service. Although this item was non-returnable, they still issued a refund to me promptly.
[A]: Negative


[Q]: I've been drinking Green Mountain's Dark Magic and really enjoyed it, however I wanted a change.  After some searching I discovered this coffee and am glad I did.  It's got an excellent deep flavor that I really enjoy.  Strong enough - yet not overpowering.  I recommend you give it a try.
[A]:
Positive
