Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

[EX Q]: First of all, don't even bother mentioning Sixty Watt Shaman in the same sentence as Alice and Chains and Soundgarden. Cantrell has more talent in his pinky than Sixty Watt has all together. If you want to check out real Stoner Rock, Kyuss and Queens of The Stone Age are a good start. This album is mediocre at best. Red Colony seems to be the only song I could really get into. Cool album cover though! Maryland must have a really lame Stoner Rock scene, because out here in CA, Sixty Watt Shaman would go unnoticed.
[EX A]: Negative

[EX Q]: It does an excellent job on mildewed wood such as decks and deck furniture without using chemical mode which is the only weak link in an otherwise strong chain. Unfortunately, the only effective chemical solution is chlorine which acts more or less on its own but cannot be used with this machine. Safe cleaners, such as Simple Green are no more effective than when used without them. Other than that, it's a great product.
[EX A]: Positive

[EX Q]: If you are a teacher, I would look into buying another audio version of Romeo and Juliet. I have been using it as a tool to get the students to hear professional actors and to then ask them to use the same skills those professional actors use (inflection, emphasis, etc.) The problem is it is VERY difficult to hear...to the point that you have to sit 3 feet away to hear it at times. This simply does not work for a classroom.
