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.
I needed to replace a calculator from a Teacher Pack. Found the perfect replacement here. It works great. Exactly what I needed. Delivery was very quick.
Great communication, Karen and Jacob took good care of us. Shipping was fast. Product is excellent quality. Thank you. -Arnold
Works perfectly! Couldn’t find these cables anywhere but once I saw them so reasonably priced here I couldn’t say no! More than happy with my purchase! Thank you!
I search something and they have it, sent an email about it with instant response and Jake helped me order it in a few mins, product arrived much earlier than I expect and in excellent condition.
I ordered a calculator late Monday night that I needed by Wednesday. I communicated with Jake several times via email and once on the phone throughout the next day. Had my calculator before noon on Wednesday. Every response to me was quick, helpful, and very courteous!! Great company and customer service. I will order through them in the future and highly recommend others to do the same.
