Customer Review

Reviewed in the United States on September 12, 2013
I have no doubt that this calculator has some impressive capabilities. Calculus instructor recommended this unit, 80 students bought it, 3 were defective. Mine being one of the lemons. My new, out of box calculator would not hold a charge.

Texas Instrument's return & warranty response: "Please be aware that your unit will be replaced with a reconditioned unit with a 6 month warranty or the remainder of your current warranty whichever is longer. You can expect between 3 and 4 weeks turn around time once you ship your unit and a copy of the sales receipt."

Very disappointed to have spent roughly $145 for a new unit only to be given a used, refurbished unit with a 3-4 week delay. Texas Instruments should be ashamed of this policy.
