My application was to control a media player remotely in a stage performance. It worked perfectly! If you need pre-planned keyboard typing with one button, this is exactly what you need. Highly recommend. ### ⭐ Not a good product *by N***A on May 26, 2025* Left light does not work and looses programming and shuts off after a few secs. ### ⭐⭐⭐⭐⭐ Programmierbare USB Dreitasten Tastatur *by F***Z on February 11, 2026* Perfekter Problemlöser. Bluetooth Tastatur funktioniert direkt nach dem Bootvorgang noch nicht, um zwischen MacOS und Windows auszuwählen. Diese kleine Kabelgebundene USM Tastatur reicht aus, um nach rechts oder links zu schalten und Enter zu drücken. Lässt sich problemlos auf jede beliebige Taste programmieren. Das einzige unsinnige ist die wechselnde RGB Tastenbeleuchtung mit Disco Effekt. Macht null Sinn. ## Frequently Bought Together - PCsensor 3-Key Mini Keypad USB Type C Wired Mechanical Gaming Keyboard Hot Key Customized Program with RGB Led for Gaming OSU Office Work for PC - BOOX Palma Mobile ePaper 6G 128G G-Sensor Front Light 16MP Rear Camera (White) --- ## 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/580236689-3-key-mini-keypad-usb-type-c-wired-mechanical-gaming](https://www.desertcart.co.uk/products/580236689-3-key-mini-keypad-usb-type-c-wired-mechanical-gaming) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-26*
