Orpat calculator is without doubt, a wonderful product at a most reasonable bargain price! I'm proud that Orpat is an Indian product, and not another of those cheap Chinese products. What I did not like about the Orpat calculator, was the very cheap, flimsy and low grade carton the calculator was packed in. Even worthless Chinese products flooding the footpaths are better packed these days. Worse still, what was really jarring, was the large, garishly cheap looking brand name and model no. printed so distractingly right next to the display. Why does the company, which proclaims it's credentials as "the largest manufacturer of calculators in India", need to indulge in such loud, abrasive marketing gimicry? Why does it not let it's product's quality speak for itself and print the logo and model no. on the underside of the calculator for happy customers to discover for themselves? I appear to be more confident about the product's quality at the moment, than the manufacturer, because I see no need whatsoever to ruin the face of the product by announcing the brand name and model no. so loudly and distractingly competing for attention. Terrible idea. ## Frequently Bought Together - Orpat Ot-512Gt Calculator (Black) - BIC Wite-Out Brand EZ Correct Correction Tape, 39.3 Feet, 10-Count Pack of White Correction, Tear-Resistant Tape Office or School Supplies - Sharpie Permanent Markers Set Quick Drying And Fade Resistant Fine Point Marker For Wood Plastic Paper Metal And More Drawing Coloring And Poster Marker Black 12 Count --- ## 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.co.uk/products/64570480-ot-512gt-calculator-black](https://www.desertcart.co.uk/products/64570480-ot-512gt-calculator-black) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-23*
