Texas Instruments TI1795SV Solar Calculator The classic mini-desktop calculator for home, office, or retail with big keys and a giant SuperView display.
Customer Review: Tough Little Calculator! (Style has changed - see photo)
I’m SO happy to see they still make this model calculator! I’ve had mine for about ten years now and use it daily and it finally died today. I’ve used it so much I wore the paint off of the point key, and pulled it out tonight to check something and the plus key (finally) stopped working. This is an awesome and very tough little calculator, the display is nice and big and very easy to read in even low light (and I have poor vision), it’s lightweight and I can easily throw it in the drawer without worrying about it getting damaged, but it’s not so light you can’t pound away on it without it slipping around (and it has two little rubber feet to keep it in place). And it’s completely solar, no batteries to worry with. I just ordered another one tonight, and I’m so glad I don’t have to get used to a different one (I key very fast and it keeps up with me), here’s hoping my new one lasts another ten years 
Update - I just got this in the mail today and FYI the style number is the same but the design has changed (see photo comparisons above, the Amazon stock photo is incorrect). The new one is bigger and rounder, about a half inch wider and longer. It’s also thicker and the key pad is ‘ergonomically’ rounded, which makes it a longer reach for short fingers. The buttons are a little bigger and there is an extra row of three at the top (rate, tax+, tax-) that I don’t need. So it will take a little getting used to, I wish it was still the smaller size, but the display is still big and easy to read and the keys are quick.

Texas Instruments TI-82 Graphing Calculator Customer Review: Graphics Calculator
I purchased this calculator for statistics, and didn’t purchase it directly form Amazon, but from a seller on Amazon in the used category. Unfortunately for me, the seller wasn’t honest in the item description. I didn’t mind that it came with some scratches or engraved with some words on it from the previous owner, but I didn’t appreciate purchasing a broken calculator. I can’t give a review for the itme since I received it broken (and arrived a week later than it should have), but I will rate my review on the seller, which is why it is makred low.

Customer Review: A True Leap
I began using Texas Instruments’ graphing calculators with the TI-83. In addition, I’ve used the TI-81 and TI-82. I’ve seen the calculators improve through the TI-83+, the silver edition, and the TI-84+ and its flavors. They were all improvements and refinements, but not revolutionary. My classroom uses them all and, except for the TI-81 and 82, it’s not a problem.
