AIRFOX K20 Ultra Compact Slim Profile LED Backlit Wireless Bluetooth Keyboard for iOS, Android, Windows and Mac with Rechargeable Lithium Battery (Black)

I was impressed with this keyboard right out of the box. I bought this for my 13" laptop, which I keep on a stand and switched over from a wireless Anker keyboard that broke after a year and a half when I spilled a drop of coffee on it. The best things about this keyboard are the size, the illuminated keys, and the quality. This is about 11" and nearly, if not identical to, the size of my laptop keyboard. It is also extremely thin. I didn't really need 7 different colors to illuminate my keyboard, this was about the only bluetooth keyboard this size that was backlit. You can choose to have it lit or not. There are two illumination settings but are barely distinguishable. Between the brushed metal bottom and sleek design, this thing is very impressive looking and it feels pretty good to type on. The top and keys are plastic, but do not feel cheap like my previous wireless keyboard. I can't comment much on the function keys and all that because I don't really use them. It took about 3 hours to fully charge but the directions state it could take 4. It connected easy. I keep it near my computer so can't comment on the quality of the bluetooth, other than I have not experienced any lag other than if the keyboard has gone into power save mode. The keyboard will, essentially turn off, if not used, although it seems to do this fairly quickly. There is a legitimate off button on the back though.There are a few issues that prevent me from awarding the Airfox K20 with 5 stars. The biggest concern is the space bar. After using this keyboard very briefly the space bar started to stick. I gently pried the space bar up until I felt it detach, but did not take off the entire thing. I snapped it back in securely and it started working fine. A day later I encountered the same thing. I applied the same fix and it returned to normal. However, if it happens again I will likely attempt to exchange it. Less importantly, It would be nice if it came at least half charged so you can get a sense of what you purchased right away. Also, less importantly, it is not always real responsive if it is in energy saving mode and you have not typed for awhile. Sometimes I might have to click it a few times before it starts to respond, a problem I did not have with the Anker brand keyboard. Lastly, the keyboard is not angled very much, and certainly not to the degree that my previous Anker keyboard was, however, it has a type of slight curvature that is comfortable on the hands and fingers.

I like this product so far, lights are pretty, and as a keyboard it works. Key pressure is satisfying, construction seems fairly solid. The only thing I would mention is that it is a *tiny* bit sluggish and keys do have a tendency to ghost now and then but not to the point of being a hindrance. I would not recommend it to anyway who needs high performance or precision, like competitive gaming requires. A lot of people have written reviews saying that the device constantly disconnects, I have not had this problem yet but will update if I see the behavior. On Windows 10 I did have a problem with Windows constantly powering down and powering up my Bluetooth adapter; by going to Device Manager > Blue Tooth > (Name of my Bluetooth adapter) > Power Management and disabling "Allow the computer to turn off this device to save power" I stopped suffering disconnects. Before you complain about disconnects I would recommend trying this fix.Update:I have experienced the disconnects that people are talking about when the keyboard goes to sleep and I do have to turn it off and back on by hitting the switch under the keyboard. Though this is a small thing it is actually very irritating, if the button where on the top and I could simply "wake up" they keyboard by hitting it that would be a lot better. Because of this I think I have to revise my rating to 3 Stars. Its still functional as a keyboard, quiet and the back lighting is nice, however these couple of UX problems keeps it from being a 4 or 5 star keyboard.

Very nicely done, great feel, responsive keys, easy to pair, good distance for your media room, dose not slide around when typing on your email (thank-you) slim rubber pads! Battery fully charged has lasted me a couple of weeks with led lighting on its lowest setting. Yes it has a power save mode and re-connects within two seconds after pushing any key, not the "any" key. Money well spent. Hopefully it gives me years of service with non-fading keys.Add a stainless steel top to match the bottom and I'll buy another one.***UPDATE***The K20 bluetooth keyboard started cycling on and off by it self, not allowing PC monitor to stay asleep when at idle. The keyboard was out of warranty with Amazon. However after making initial contact with the seller, within a week I had a replacement at no charge.

This keyboard is probably the nicest one I've ever had.A NOTE TO WINDOWS USERS:The f-keys and escape key by default will not work unless you hold the Fn key down. This is because you are expected to assign an operating system to the keys by pressing. Failing to do this will require you to hold the Fn key down in order to use any of these keys, which means no F-Key shortcuts.Fn+W for WindowsFn+Q for AndroidFn-E for iOSI've seen some reviews mention this as an annoyance or defect, when really it's just user error.This keyboard is small - like a laptop. It takes a little bit of getting used to.It has several different backlight colors, and the light turns off after a minute or so of inactivity to save power - I love this.I love that it's rechargeable, and seems to have no issue lasting through a full day of frequent use.I have had virtually no single instance where transmission between it and my bluetooth receiver 10 feet away has not worked.It has a metal casing and is a really sleek, durable design.Don't hesitate to buy this keyboard.
