  • Summary: The picture in the advertisement is not the calculator I received. It however has the same functions as my orginal calculator that is in the advertisment. This new calculator has smaller buttons and harder to read the written functions on it. I would not but this caculator again.

Fantastic Sentry CA656 Calculator

  • Summary: You would never be able to tell that this calculator was used. There are NO outside wear, and all the keys work perfectly. Rarely do you find a calculator that has all these functions, and I am VERY pleased with this auction.
