Title: Not great
Review: I was disappointed in this calculator. Since it has no battery backup, I can't use it in my office after about 5:00PM because it's not bright enough to generate the power needed for the solar cells. It seems almost unbelievable that they would design something like that, but they did and it does'nt work in low light situations, which makes it useless 50% of the time for me.
