TI-85/TI-86
Ti-85 and TI-86 are the best calculators ever made. Of course without CAS. CAS is very nice feature but, as we can see, it leads to more complicated user interface. My preference is use PC/notebook insted them. TI-85 and 86 are powerfull calculators with genial user interface. It is pleasure to use them. Even that they have "obsolete" black and white low resolution display. Just trust me :-).Verified purchase: YesCondition: Pre-owned

TI-86 Rocks!!
if you find one of these, bid on it, or buy it now!, lacks flash memory, but for solving stuff right away you should type less compared to a ti83/84, good for school as college, from pre-algebra to calculus, ive been on ti 89, voyage 200, ti 50g, but always relapse on these simple yet powerful calcs, cant miss on these, and the best , -you can excel at a SAT, etc , its allowed on all tests . 5 stars , last thing, they are heavy duty, well built.Verified purchase: YesCondition: Pre-owned

Great product.
This is my third TI-86. They lack a start menu like most which I really like. Takes you right to the input screen for quick easy use. The other features are easy to access via buttons.Verified purchase: YesCondition: Pre-owned

Saved me so much money
I got this graphing calculator for under $30. And it seriously had every single capability I need it to for college. I am really thankful I found this product for sale, because I was about to shell out $130 for one of these things just so I can pass math. They provide calculators in k-12 but not in college. Seriously surprised at how well this product works for how cheap it is, I honestly was a little worried at first. I am so thankful for the person who decided to sell this product, thank you!!!!!!!!Verified purchase: YesCondition: Pre-owned

Graphing Toward Graduation
A great little calculator that just made a high school freshman a very happy little mathematician-in-training. She had experience with the same kind on a school-use loaner, thus was ecstatic to have her very own instrument to use for the remainder of her high school years, instead.Verified purchase: YesCondition: Pre-owned

Perfect Calculator
I was concerned about the display quality. Some of the TI-86 calculators I have seen in the past have 'burned in' screens, but this one was perfect!Verified purchase: YesCondition: Pre-owned

TI-86 as alternative to TI-84
The calculator condition is excellent. The function is equivalent to ti-83/84, the resolution is lower than ti-84 CE, but good enough for general graphing purposes. Highly recommended as a starting graph calculator. The price/value ratio is probably the highest among the ti-8x family. We lost a ti-84 CE and found this one as a good alternative.Verified purchase: YesCondition: Pre-owned

Junk !
An entire row of numbers is dead. I can't use a calculator that does not have a 1, 4, or a 7. This is garbage, the description said the calculator was in good working order. It was either not checked for the most basic operation or intentionally sold defective.Verified purchase: YesCondition: Pre-owned
