He loves it! He loves the slight sounds the calculator makes when he presses the keys. He loves the color and the size. He has enjoyed using this since he got it, school starts next week and so he will have something he likes and needs. Hard to sometimes meet his sensory needs and basic school needs all in one item. The keys are big, stand out and that is a plus. ### ⭐⭐⭐⭐⭐ Mr Pen calculator *by K***N on August 24, 2026* I love it! The size is great I love the pink color and personalized note is so cute. Thank you I will definitely buy again. The calculator needs 1 AAA, very satisfying sounds, and they won’t be loosing it, because it’s big, the kids love it too. Win win. Love the mustache sticker too ☺️ ### ⭐⭐⭐⭐⭐ Cute, Easy to Use, and Worth It *by J***R on September 23, 2026* I really like this calculator. The display is nice and clear, so the numbers are easy to read without having to stare at the screen, and the button layout makes sense right away. The mechanical keys are probably my favorite part. They have a really nice feel when you press them and make the calculator more enjoyable to use than the usual flat-button ones. The buttons respond well, and the calculator feels stable on the desk instead of sliding around while I’m typing. I also like the size. It’s big enough that the buttons aren’t cramped, but it doesn’t take up a ridiculous amount of desk space. The purple color is cute too, which is honestly part of why I chose it. The solar-powered feature is another nice bonus because I don’t have to worry about constantly replacing batteries. For the price, I think it’s a really good value. It’s easy to read, functional, sturdy, a good size, and actually looks nice sitting on my desk. I’ve been very happy with it so far and would definitely recommend it. ## Frequently Bought Together - Mr. Pen Mechanical Switch Calculator - 12 Digit Large LCD Display, Pink with Big Buttons - Office Mousepad with Gel Wrist Support - Ergonomic Gaming Desktop Mouse Pad Wrist Rest - Design Gamepad Mat Rubber Base for Laptop Computer -Silicone Non-Slip Special-Textured Surface (01Pink) - Der Rose Set of 2 Succulents Plants Artificial Mini Fake Succulents Plants for Office Desk Accessories for Women Pink Home Decor --- ## 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.com.eg/products/550859287-mr-pen-mechanical-switch-calculator-12-digit-large-lcd-display](https://www.desertcart.com.eg/products/550859287-mr-pen-mechanical-switch-calculator-12-digit-large-lcd-display) --- *Product available on Desertcart Egypt* *Store origin: EG* *Last updated: 2026-10-03*
