Texas InstrumentsTI-30XIIS Scientific Calculator, Black with Blue Accents

Very reliable calculator for the easier stuff, not expensive at all with really fast and reliable shipping. Saved me before a math test! Stays alive for a while and is easy to find buttons rather than search for a while

I used this for the last four years of my career as an engineer. I was going to buy a HP, but their quality has gone down greatly over the years.

My son is in 8th grade and needed a scientific calculator for school. It worked well for all of his assignments. It lasted all year and held up fine, considering it was probably tossed in/out of his book bag. The price was very reasonable, definitely recommend this.

Great for college.

"I recently purchased the Texas Instruments TI-30X IIS Scientific Calculator with Black and Blue Accents, intending to use it for math tutoring. Upon arrival, I discovered it was a used unit, which was a surprise since I didn't realize that option was selected during purchase. While I could have opted for a 'used - very good' condition at a lower price, I had expected a new product. Due to needing the calculator urgently for a tutoring session the next day, I chose to keep it rather than return it.Initial Disappointment: My primary concern was the discrepancy between my expectation of a new calculator and the used item I received. This warrants a mention, as clarity in product descriptions is essential.Functionality and Performance: Despite being used, the calculator functions perfectly as advertised. All buttons are responsive, and the display is clear. It performs all necessary scientific calculations accurately for now. I will rewrite a new review after more than one use.Reliability and Durability: I have personal experience with the TI-30X IIS, having used one for over 13 years with consistent performance. This reinforces my confidence in the reliability and durability of Texas Instruments products.Value and Pricing: While the used condition was unexpected, the calculator's functionality is undeniable. It's a well-regarded scientific calculator that meets the needs of students and professionals alike. However, I would recommend that future buyers carefully check purchase options to ensure they are getting a new or used product that meets their expectations and budget.Overall Assessment: Though I was initially disappointed by the used condition, the calculator performs flawlessly. Texas Instruments continues to deliver a reliable and accurate product. I would rate it a 4 out of 5 stars, with the deduction reflecting the initial confusion regarding the product's condition. If you need a reliable scientific calculator, the TI-30X IIS is a solid choice. Just be sure to double check the sellers condition.Pros:Accurate and reliable calculations.Durable and long-lasting (based on past experience).Clear display and responsive buttons.Cons:Initial confusion regarding the product's used condition.Buyers should pay close attention to the product condition that is selected.
