As long as longevity isn’t required
Color: Graphite, Style: Keyboard
Love this keyboard, I chose the ProtoArc EM11 NL Bluetooth Ergonomic Mouse to go with it. Could not be more pleased with quality and heft of the keyboard specially at the price point. Whisper silent and easy to pair. Excellent choice.
******UPDATED******
Had to come back and downgrade to 1 star. Keyboard quit on me after 3 months. Phantom keystrokes, like I was holding down one letter. It was a slow burn until I couldn’t take it anymore. Thought it was a one off. Replaced the batteries etc. If you just need something for a month or so while waiting or saving for something better, go for it. Totally fits the ‘you get what you pay for’ idiom.

Great Keyboard
Color: Graphite, Style: Keyboard
I bought the keyboard only, because I already had the bluetooth mouse. This is a very good keyboard. I was concerned when ordering that the keys maybe be mushy without having seen a display, but I've not found them to be so at all. The keys do not click loudly like every other keyboard I've ever used, but the keys are every bit responsiveness and snap like others. After using it a couple hours, I don't really notice the lack of clicking . . . and found it actually does have its own distinct muffled sound.

Well Worth the Money
Color: Graphite, Style: Keyboard
I bought this keyboard after my last bluetooth one crapped out. I wasn't looking for anything fancy, and it's not. But it is comfortable, and I like the way the keys feel. Honestly, I even like the way it looks.
The only downside is that one of the control buttons near the shift button will erase an entire sentence or two if it is accidently touched. That's annoying, but not enough for me to give it a four star.
It's fairly quiet. I actually like the way it sounds.
I use it every day, sometimes for a couple of hours. The batteries are going strong.
I am glad I didn't go for a more expensive option. It doesn everything I want it to.
It's compatible with my tablet and connects right away. I don't even have to reconnect it every time. I just start tapping the keys and it is ready to go fairly quickly.
Over all, this is a great value for your money. I highly reccommend it.
