Texas Instruments® External Battery for TI-Innovator™ Hub

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 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

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.

I am a first-time customer but will definitely purchase items from Underwood Distributing Company if I have a need for their products in the future. I purchased an authentic Texas Instruments battery and replacement charging cord for a TI-84 calculator. The cost of these two name brand products with shipping was still less than the cost of the battery alone through Amazon! Each item came wrapped individually in bubble wrap then placed in a bubble wrap mailer. Shipping was also very quick. I can't say enough about how impressed I have been from start to finish with my purchase.

I placed this order and I believe it was the next day, someone got in touch with me to tell me that they didn't have the specific item in stock to ship out right away, that it would be coming the week after. They gave me the option to keep my order or to get a refund. I told them I didn't mind waiting a bit longer. I got what I ordered, exactly as I had expected it! Customer service was amazing and exceeded every expectation!

The ONLY place that gave me exactly what I was looking for at a decent price!!!

This is my first time using this company. I will definitely be using them again. They had a great deal on a specific calculator that I had been looking at for awhile. My item was delivered earlier than I expected. Great company.

I ordered a replacement for my calculator, shipping was and the item was easy to find and high quality!

SOOOOOOOO CUTE! And affordable compared to Amazon :) arrived just in time for my statistics class!

I recently purchased the TI-34 MultiView Scientific Calculator EZSpot, and I love that it stands out from the plain black ones! The blue and yellow design perfectly matches our favorite team's colors—the SDSU Jackrabbits. It's a fun way to show some school spirit while getting school work done. The calculator works great, and the vibrant colors make it easy to spot and not confused with other students' calculators. Highly recommend for any South Dakota State Jackrabbits fan!

I was excited to get a more unique colored calculator. The price was very reasonable and it came quite fast. I will be shopping with them again and recommending them to friends!

Great battery and fast shipping.
Product worked great
