Example Input: I am training for a half marathon.  At the start of my training I wasn't taking cherry juice.  As I increased my long runs each week my knees and hips were so sore.  I started to take this cherry concentrate and ever since then I have felt pretty good.  I take the juice every morning with my breakfast.  It has a very strong flavor but mixes well with apple or orange juice.  The half marathon I'm running in is this weekend and I feel ready for it thanks in part to the cherry juice helping reduce the pain.  This stuff works for me.
Example Output: Positive

Example Input: this isn't as easy as it looks, doesn't came with enough yellow frosting, and the frosting doesn't stick very well. My 5 year old did like making it though.
Example Output: Negative

Example Input: Though this micpreamp has several weaknesses, I give this 5 stars because it's just perfect for what I do.  I've been finding ways to record vocal in convenient way with good quality. Everyone told me I'm suppose to get audio interface for good vocal recording, but audio interfaces always ended up with frustration.  After seeing several reviews of Icicle, I was going to return this, but once I used it, I don't think I want to return it anymore.  This preamp is way beyond my expectation.  However, like I mentioned above, it has weaknesses so this might not be a solution for many people  1) it has no headphone jack for direct monitoring 2) no asio driver 3) only one input 4) does not look strong so always be careful  If you are a person like me who just to need to record vocal conveniently using easy software like cool edit or audacity, you won't regret.
Example Output:
Positive
