Have ordered replacement batteries for graphing calculators on two different occasions.Very happy with the price and the shipping fees are reasonable. Each time the delivery was on time or earlier than promised. Great company to do business with.

My high schoolers needed this calculator aid in homework and it works great.its the same one they use in their class and they are beyond happy with it.

ordering was easy--there were absolutely no problems...I had a question about
the items ordered and some tax exempt questions, but all questions were
handled quickly and efficiently. I wish all companies were as easy to deal with.

Working with Underwood was a great experience. My sales rep was responsive, patient and incredible helpful as I explored my options and refined my order. Shipping was also very quick and my products arrived in great shape. This is the second major order I've placed with Underwood and I would not hesitate to order from them again.

I am looking forward to conducting future business with Underwood Distribution Company.

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!

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

The Ti 84 launchpad board and RGB led board are hard to find new for just a single user and definitely not at such a good price. Prompt shipping and everything arrived well packed. Seriously great source if you are looking for small quantity at great value. Thanks!

I teach middle school and wanted reliable calculators, at a good priced, and in a distinct color so everyone knows who they belong to. They were well-packed and arrived quickly! I am so pleased with my purchase and will keep this company in mind for future needs.

I have be searching for this cable for over a year! I went to Circuit City, Best Buy and Amazon. NONE of them had this cable. FINALLY I found this cable and I bought in on a desperate hope that it would be the right cable. IT IS!!!! THIS CABLE WORKS FOR CALCULATOR to CALCULATOR DATA TRANSFER!!!

My current order of graphing calculators was placed and ordered so quickly. Underwood Distributing Company made this process easy and I appreciate the timeliness along with the great price. THANKS!

Underwood Distributing was so easy to work with on getting calculators for my classroom! They were so nice and kept me up-to-date with the status of my order. I received my order very quickly, and I am very happy with the purchase.

I am very satisfied with the promptness and diligence in which my order was processed. The teachers were able to receive their needed supplies on time.
