Keep ample supply of batteries nearby
Color: Graphite, Style: Keyboard
his keyboard does exactly what I needed it to do—stay quiet. No loud clack-clack echoing through calls, even on sensitive audio. It’s a solid choice if you’re working around microphones or just prefer a softer typing sound. Connectivity was easy, and it’s been reliable so far. The keys feel comfortable once you get into a rhythm. That said, the spacing is just slightly different from my previous keyboard—barely a millimeter or so—but it’s enough to throw you off at first. There’s definitely a short adjustment period before your fingers recalibrate. Also, it doesn't blow through batteries super fast, but I promise you'll want some spares handy because Murphy's Law dictates that you will be in the middle of something important when they go out! Overall, a dependable, low-noise keyboard that works well once you get used to the feel.

I am very happy!
Color: Graphite, Style: Keyboard
No issues. Keyboard works great and connects flawlessly to my laptop. Can't imagine any other problems. It does make a little clicky noise when typing but not overly loud or annoying and not as loud/annoying as my work computer keyboard. That keyboard has a very thin, plasticy, sharper, cheaper sounding click and this has a more subdued, heavier duty sounding click. I like it much better. It seems dampened maybe. It's hard to describe sounds but I find it way less annoying than any other keyboards I have used. I am extremely happy with its size and still having the full keyboard and numbers.

Simple, reliable, and very comfortable to use
Color: Graphite, Style: Keyboard
This keyboard is exactly what I was looking for. Setup was quick and easy, and the Bluetooth connection has been stable with no lag or dropouts. The keys are comfortable and quiet, making it great for everyday typing at home or in the office. I really like having the full numpad while still keeping a relatively compact size. The keyboard feels sturdy, and the spill-resistant design gives some peace of mind. Battery life has been excellent so far, and it works smoothly across both Windows and Mac. Overall, it’s a solid, no-frills keyboard that does its job well. Great quality and performance for the price.

Feels cheap, but hard to complain at this price
Color: Graphite, Style: Keyboard, Color: Graphite, Style: Keyboard
This keyboard definitely looks and feels very budget, and the plastic construction makes that obvious right away. The whole board has a strong plastic feel, and if you twist it even a little bit, you can hear the frame making plastic creaking noises. It doesn’t exactly feel sturdy or premium. The key feel is also pretty mediocre. The keys feel a bit mushy and not very satisfying to type on. If you’re used to better keyboards or mechanical ones, the typing experience here will probably feel pretty underwhelming. That said, I can’t be too harsh on it. This is a very cheap keyboard, and for the price it does the basic job. It connects easily over Bluetooth with no lag, and it even comes with the AAA batteries included. So it’s still a decent value for a simple everyday keyboard. Four stars feels fair for what it is.
