Ultra light and portable. Eye catching. However, more pressure is required for certain keys (those located near the hinges) in order for your device to register the key command. A little disappointing when you're typing a long thought and you have to go back to fix the typos. It's also a little cramped. I want wasn't expecting the luxury if a full sized keyboard, but even with my smallish hands (size medium in disposable gloves) I feel cramped. Almost there, though. ### ⭐⭐⭐⭐⭐ Excellent foldable and portable keyboard! *by N***. on Reviewed in the United States on March 15, 2016* Battery lasts for a long time as advertised. Typing on the keyboard was a smooth experience. Doesn't take that long to get used to typing on this nice device. Been using it for 3 weeks without any hiccups. I'm mainly using it for school in conjunction with my android tablet. ### ⭐⭐⭐⭐⭐ Durable and compact. *by E***N on Reviewed in the United States on July 31, 2015* Cool little keyboard, connected easily to iPad after reading the instructions which came with it. My favorite thing is the way it folds up: 1.) this protects it when it is bouncing around in my briefcase. It's really pretty small when it's all folded up (see pic) 2.) shutting it automatically turns it off and disconnects it from the iPad saving battery life. I received this product for my honest review. --- ## 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.sk/products/73524633-cooper-optimus-folding-bluetooth-keyboard-for-asus-transformer-book-t100](https://www.desertcart.sk/products/73524633-cooper-optimus-folding-bluetooth-keyboard-for-asus-transformer-book-t100) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-06-11*
