Robust and so far surviving our 12 year olds year 7 ### ⭐⭐⭐⭐ Really good product no issues at all. *by C***N on 21 June 2025* I brought this because I am studying for an electrical course and needed a good scientific calculator I was allowed to take into exams. I did alot of research and this was recommended quite a few sites. Without doubt it's feels like one of the easier calculators to use. Screen clarity is good and has a bunch of options as well to help adjust to needs. The quality is great the hard case protects the calculator and mine is as good a year old on etc. Battery is faultless no issues and it has solar point anyway. Great value for money and as shown the functionality is great as can change how data is given. If I had to complain about anything when it's new you may find yourself on casino site to see how to do whatever function if can't work out however the guide is good there and a quick Google will find someone has a video somewhere because it's a good product and people have invested in it. ## Frequently Bought Together - Casio FX-85GTCW Black Scientific Calculator - Helix Oxford Maths Set with Storage Tin - 10 Piece Maths Equipment Set - Zebra Pen Z Grip Black Ballpoint Pens with Pocket Clip 8pk, Retractable Black Ink Ballpoint Pens, Reliable Black Biro Pens Multipack for Everyday Use Design, New Pack Size 8pk --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/514910333-casio-fx-85gtcw-black-scientific-calculator](https://www.desertcart.tw/products/514910333-casio-fx-85gtcw-black-scientific-calculator) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-08-02*
