Input: Consider Input: As a student of jiujitsu i understood alot of the moves but i found that without previous knowledge these pictures and instructions were difficult to understand. I feel there is alot of good information but not worth buying.

Output: Negative


Input: Consider Input: 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.

Output: Positive


Input: Consider Input: I use this to listen to ear buds at work but the computers are hidden under the desk so this allows me to have access to the jack. i can move around my cubicle with ease with these.


Output: Positive
