Review: Great product for quick switching Samsung and Windows - Initially I was skeptical about getting a keyboard without a rechargeable battery but this keyboard is great. Very high build quality, great range and it works with all my devices flawlessly. I simply use the rechargeable cells from desertcart and the batteries last months for me.
Review: It's affordable, but is it worth the bag space? - This keyboard is ultra-thin and lightweight. The connectivity, between devices at that (including non-Samsung), is excellent. If you need an affordable travel keyboard, this will work. Battery life is great. It takes two AAA batteries. +Downsides: 1) No 2.4 Ghz connectivity (BT only) 2) No backlight 3) Poor keys quality +Considerations: Some keys may not function normally with some devices (specifically function keys like Dex button).

### ⭐⭐⭐⭐⭐ Ease of use.
*by P***R on March 19, 2023*

I live the easiness of this Keyboard from Samsung. The Keyboard automatically recognizes my tablet and phone . Pairs immediately! Very responsive, I reply to texts now by typing with both hands, it has turned my tablet into a PC. So easy , especially with Samsung X, I also have paired a Bluetooth Mouse , allows me access every thing I need and I get there fast, using also my stylus which came with my phone. At this price, and you own anything Samsung and maybe this Keyboard will connect to any brand via Bluetooth. If you buy one know, I'll consider my review helped. You also have a 30 day money back guarantee therefore, at this price on Amazon.com. Get a stand to hold your tablet or phone, you don't need it that top of you but having your mouse/ Keyboard combo close to you gives you freedom and your multitasking becomes incredible , fast and efficient. I wouldn't steer anyone down the wrong path abd I do not work for Amazon. I work for the future buyer I stand straight up and I'm proud of Myself. Fred
