Worked great in the calculator

The calculator arrived in excellent condition and functions exactly as described. I am pleased with the quality and overall performance of the product. The only drawback was the delivery time, which was longer than anticipated. Aside from that, my experience with this purchase was very positive.

Very quick delivery. Great price. Product is exactly as represented and needed. Kid's calculator is once again working as required.

Everything was quick, smooth, and as advertised. We couldn't be happier with our purchase!

Needed a battery for my Nspire CX, they had the cheapest battery online while amazingly also still being OEM, shipped fast, can't recommend enough.

Good pricing and very fast shipping

Genuine TI batteries for calculators are not so easy to find these days, and if they are available, makes it easier to troubleshoot an issue such as battery replacement. An example is the Texas Instrument calculator known as TI-nSpire which were apparently constructed with different orientations of the receiving pin socket. I couldn't tell what the problem was until I obtained the authentic OEM battery and deduced that the pin socket was reversed for most of the photos describing battery replacement. Original parts eliminate the doubt of compatibility when you are experiencing problems.

I am a math teacher in Ogden, Utah. We have ordered from Underwood twice now, buying TI-84 Plus CE graphing calculators both times. They were easy to purchase, a great price compared to others, and arrived quickly. No complaints here! Definitely recommend!

They answered my phone calls and emails immediately, were super helpful and quick with quotes and orders, and delivered the products within days of placing our order. Everything arrived quickly and perfectly. This was a great experience.

I have ordered calculators from Underwood Distributing for so many years that I have last track of the time. They are always quick to answer my emails and they get the product I need shipped out asap! 10/10 recommend Underwood!

Excellent service

Fantastic company and product. Stellar to work with year after year.

I have been searching for a replacement charger for my calculator for ages and struggled to find something that fit. I was so excited to find Underwood Distributing Co! They had a cord for a good price and they even had replacement bumpers for the calculator! I did not even know you could buy those! My 10 year old calculator is looking brand new now!

Had the product I needed. Received it very fast in excellent condition. Thank you.

Cable works.

Great prices and fast shipping!
