Excelente teclado, es muy cómodo y práctico para cargar 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

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 was able to use this on a Kindle Fire tablet with Bluetooth. It paired easily and worked well enough, although, I was severely reminded of how nearly everything, these days, requires using a mouse. I'm a bit of a power user with a keyboard, so I was able to get by with substituting the UGREEN for some ordinary tasks but, if you need a mouse, you need a mouse. I was able to do a couple of Spanish lessons on Duolingo and had no trouble using a quick ALT+TAB to switch between windows, which is something I can't do so easily with the touchscreen. Of course, mouse functions on the tablet are handled by the touchscreen, so that's to be expected. It also works well with my Linux computer, including volume controls. This is not a keyboard that I would use for everyday work at home, but if I needed to be able to switch between different systems in the field, or even in a different room, this would be my first choice. I'm adding 1 star just because of its versatility. I switched between a Linux computer, a TV, and a tablet fairly easily. My tablet used Bluetooth to connect. The TV has a USB port for the 2.4g dongle, and the Linux computer also used 2.4g, although it could easily use Bluetooth, if enabled. I plan to use this for an upcoming Raspberry Pi project, which will have Bluetooth installed. It seems pretty solid. I've opened and closed the battery cover door, several times, to get the 2.4g dongle out, and it shows no signs of falling apart, unlike my expensive mouse that I have to tape up to keep the battery door from falling off. The keyboard is lightweight and compact. Read more

What Iike: - Inputs are very responsive via Bluetooth and USB adapter - The keys feels great when pressed - Easy to pair with my Windows 11 computer and Samsung Z Fold. Lightweight - It has a nice built quality What I don't like: - No LED to indicate the keyboard is "on". This is for those who forgets to turn off the keyboard. - It doesn't auto turn off when it's not in use for long duration Read more

This keyboard is super lightweight and compact which makes it a good option if you're planning to haul it in your laptop bag. The layout is the same as my MacBook Pro, so the key locations are very intuitive. There's 2 feet that fold, so you can adjust the incline up or down. The build is a very lightweight plastic, and while it doesn't feel premium like a MacBook keyboard, it's also not flimsy at all, maybe a bit more hollow feeling when typing, but does not bother me at all. I was using a Logitech MX Keys for my work from home setup since 2021, but recently I spilled a protein shake all over it, and I had to pop the keys off to really clean my mess well. It was a tedious job but it worked, however while putting the keys back in place I managed to damage a couple keys which made using the keyboard cumbersome. I considered repurchasing the Logitech keyboard (it's an excellent premium option), but couldn't justify the purchase. This smaller keyboard is such good value. Firstly, it comes with a USB dongle in addition to having bluetooth built-in. I use it on bluetooth and have no complaints, connection was effortless. It works on AAA batteries and only time will tell on battery life. Been using the keyboard for about 3 weeks now, 5 days a week, and no sign of slowing down! The only features that I miss from my old Logi is the number pad to the right, and the fact that the Logi was rechargeable via USB-C. But it was also 4 times the price of this little one. Highly recommend as a good value for money. Read more
