Input: Consider Input: Naader was my first yoga teacher. When we moved out of state, this video was my link to the best yoga routine I have ever done. I tried other instructors and other videos, but Naader's approach is the best -- a balanced mix of yoga instruction and inspiration. I have shared this tape with many friends (who then bought their own copy!) and they all agree that Naader's instructions are easy to follow and the pace is slow enough that beginners can figure out what is going on before the next pose; but not so slow that experienced students get bored. Furthermore, since he is doing the poses along with the student, he knows just when to offer that extra word of encouragement when you are about to give up! I find something new to ponder each time I listen to this tape. Naader's words are from the heart and they reach out to touch your heart as well as your body. Buy this tape and use it!!

Output: Positive


Input: Consider Input: Read her, you will enjoy your time with her characters. Strong women, strong men, some bizarre quirks in lots of characters.

Output: Positive


Input: Consider Input: Short and simple: This charger did not charge my laptop's battery unless the computer was either off or at least in standby mode with the lid closed.It could keep the computer operating while plugged in, but it wouldn't charge my battery. I've seen other reviews with different results, but for me, this thing was pretty much useless.


Output: Negative
