Review title: solar power alone doesn't cut it
Product review: Bought this calc because usually TI makes a good product. Had to return it because the solar power just doesn't cut it - unless you are in a VERY well-lit room, forget it... my chemistry class has decent lighting, and it still barely works there... save some frustration and get a dual power - you don't want to be taking a test and have this thing fade out on you. Still like TI calculators all around, just avoid this one.
