As a teacher, I’m always searching for tech tools that make my classroom run more smoothly—and this UGREEN K551 Slim Quiet Wireless Keyboard does exactly that. I use it to control my Promethean panel from across the room so I can keep my focus on my students while still managing slides and notes. The plug-and-play setup was effortless. I plugged the included USB receiver into my panel, and it connected instantly. The range has been excellent—I can type from anywhere in the classroom without lag or interference. The keys feel crisp and responsive, and the compact design makes it easy to carry between my desk and other workstations. While the keyboard feels a bit light and plasticky, the build quality is decent for the price, and it’s been dependable so far. I haven’t even had to change the batteries yet, which is a plus. I haven’t tested the Bluetooth mode yet, but based on how well the wireless dongle works, I expect it’ll be just as smooth. My only two wishes for future models would be: 1. An integrated trackpad for quick cursor control. 2. A numeric keypad for grading and data entry. Overall, this keyboard offers great value for the money. It’s reliable, lightweight, and comfortable for long typing sessions—an excellent choice for teachers or anyone who needs flexibility and dependable wireless control. Read more

I like the quality of keys on the keyboard and I love how clicky they are. I tried it with my tablet both on Bluetooth and wireless connection. It either takes a long time to connect or there's an error where you have to use escape key before you start typing. Once it starts typing it works great! I also like how portable it is and it's lightweight but well built. Read more

Excelente teclado, es muy cómodo y práctico para cargar Read more

Has a function lock so I don't have to keep pressing Fn every time I want to use F5. I placed it on top of my previous full size keyboard and it seemed to be mostly the same size, minus the arrow key and numpad area. Primarily use a Windows PC, but also tested it out on my Samsung phone with Dex and it's just a single button to swap between the devices. Also uses AAA batteries which means it doesn't have an expiry date like other products. And really nice and slim on top of all that. This will probably be my new go-to, once I confirm any typing mistakes I make are just an adjustment period. Also, I gotta test the dongle too. EDIT: On my Windows machine everything works perfectly. On Karabiner and MacOS the keyboard is Mac friendly by swapping Win/Alt, which would actually be very useful normally. But since I used Karabiner and will never get used to MacOS hotkeys, I did have to add some lines to swap the two buttons. Then my Karabiner file works as is. Ask AI to generate this for ya, a bit easier. Read more
