“I was pleasantly surprised as to how compact this keyboard is - about 6". However, the keyboard is tactile so it's easier to use than your smartphone. My minor niggles are: the charging port is not a micro USB socket; there is something about some of the keys that need two presses to send the command (if you're using this on a Pi you will find it annoying - ~"| being the ones that got me), I had hoped it would be Bluetooth, but the dinky usb wireless device that hides away in the keyboard is probably far cooler; battery life isn't great, but adequate.
I know I'm being picky on the downsides, but its positive points and the price make it a great buy.”
“Absolute solid mini keyboard with supplied adapter. Just charge up the keyboard first with supplied cables. Add wifi dongle to pi. Then power up and switch on keyboard. Easy as that. Great item. Built to last. Recommend.”
“It works great, easy set up. It’s slightly smaller than I imagined, so my big fingers struggle a bit with size of keys. Note, the keyboard layout may need changing depending from US-Eng.”
“This saves so much hassle in terms of not needing a wired keyboard and mouse to set your Pi up before you can SSH in. The only downside is that you have to be fairly close to the pi to use it otherwise it occasionally loses it's connection.”
