Here are the “good” and “bad” on this product.

ADVANTAGES
.
1. PRICE: I was able to purchase ten for $30. Although “Used,” all were functional.
.
2. BRAND: Texas Instruments were among the first firms to market calculators in the early 1970s. I owned its first scientific model – $175. It reduced my need to calculate statistical equations from scratch and saved me hours of tedious work. My possession lasted 20 years. Since then, almost all future purchases were TI. Although I have tried Casio and no-name brands, the most dependable and durable was this brand.
.
3. FEATURES: All basic calculator features were present. Most important was the solar power strip, eliminating the need for batteries. A sliding plastic cover kept the keys protected from dust and physical damage.
.
4. DURABILITY: It is “classroom and kid tested.” If the product can survive elementary children, it will last for years. Everyday at school is a torture test with the constant dropping to concrete floors, being tossed into a basket, and poked by little fingers.

Customer Questions & Answers

I’m confused. Some people are saying this teachers kit comes with the yellow storage caddy. Others are saying it does not. Which one is it?
Answer: Mine came in the yellow caddy.

Does this product have 10 calculators to a pack?
Answer: Yes! I received 10 TI-108 calculators and the yellow carrying case. They held up very well after this past school year.

I have high schoolers with math deficits – is it possible for you to press the negative sign before you enter the numbers?
Answer: You don’t press minus for negative numbers. There is a +/- key for that. You can press it before or after you enter the number that should be negative.

What does the storage case look like? I currently have 2 sets with yellow plastic cases. Is this what these come in?
Answer: This item does not come with the case. Just 10 calculators.

Do they run off batteries and if so, how hard are they to change the battery?
Answer: I’ve never had to do anything with batteries, just let them work of solar power.
