Underwood Distributing was super fast. I sent my daughter a new pink calculator to her college. It will make physics a little more enjoyable for her. Would purchase here any time.

Love that I can use my Inspire calculator now that I have the 84 faceplate! (I never could get used to the Inspire faceplate, so it's been sitting unused for 10-15 years now)

Calculator was hust flashing on and off and a new battery fixed it right away! This is also the approved battery replacement for texas instruments and buying off brands can ruin your calculator

Fast shipping and item as described! Cheaper and faster than Amazon.

As a high school math teacher, I keep a few of these batteries in my desk for student calculators. They are great, and reasonably priced. I am actually placing my third order of 5 batteries.

I ordered a set of ten Texas Instruments TI-15 calculator/arithmetic trainer calculators for students of mine who need them for working with fractions having unlike denominators and for converting fractions to decimals and vice versa. The packaging was sturdy, the shipment came within the timeframe I was given, and the pricing was very good.

Got the calculator my daughter needed for March class and was able to get the cover. Shipping was very quick. Zero issues.

Recommended by chatGPT, items came super quick and work perfectly. Highly recommend!

Product was as advertised, great condition and well packaged for shipment. Shipment was good, I would buy again.
