It definitely takes time getting used to typing with this split keyboard since most of us have been typing on a regular layout keyboard for years.Works with multiple operating systems, Windows, Android, MAC/IOS. Wish the keys were labeled with different operating systems as well, such as the command icon for IOS devices. I love how it connects to three channels, so you can connect to multiple devices easily. Some other keyboards have an extra row on top for shortcuts but with this keyboard, those shortcuts keys are shared with the number buttons. You just have to press the FUNCTION key as well as the respected number key/shortcut that you are looking to complete. I was even presently surprised that the screenshot shortcut key worked on IOS 13 as on my Logitech k380 keyboard, that shortcut key is not working. I though it was an IOS issue. The keyboard shuts off with closing and turns back on when opened. If you keep open for an extended amount of time, all you have to do is tap a key to quickly reconnect again. When the screen shuts off, you can also tap a key once to turn on screen and tap any key again for faceid and unlock device. Another great little feature that I like with this keyboard, that others are missing, is the CAPS lock. This has an LED that lights up when you turn on CAPS lock. There is also a shortcut where you can check the battery remaining power, each LED flash represents 25%, 4 flashes would = 100%. When battery is running low, the LED will flash red. I must say I have a Logitech and Arteck external keyboard and I like the key travel and typing feel on this one the best. Those keyboards are also elevated a little and I was always under the impression that you needed that for a better typing experience but it seemed to always give me wrist pain with those slightly elevated keyboards. With this one, even though it is completely flat, I am not getting any wrist pain. It must be due to the ergonomic design. My biggest concern is the split keyboard and the times it slows me down with the smaller top row keys. For example, I tend to press the “B” with my right hand but it is on the left hand side. I am sure it a bad typing habit on my side. I hope I can get get used to this type of keyboard and still use a non split keyboard for work and go back and forth between the two and not disrupt my typing experience.I think they could of squeezed in another top row for dedicated shortcut keys so you don’t have to push function keys. Another design flaw is the Micro USB charging port, I was really hoping that it would of been USB C at this point in time. I do have a micro USB adapter to C that works but just another piece that you would need. Would of liked the charging cable maybe be on the side instead of on the top of the keyboard. As you can see from the picture, the one LED, when charging bleeds into the other LED. You can still use the keyboard while charging which is a benefit as well.I think when it comes down to it I would rather have something with a larger size than so compact. As I saw myself stopping a few times to access shortcut keys or use the smaller number keys on the top. The letters are a perfect size which especially help when getting used to this design and typing keys .. prevents you missing the keys.With a little practice, I can see this being 2nd nature typing, and ideal for compact travel.Me mainly using at home, think I am going to opt for a larger keyboard .. Since I like the typing feedback and travel, I will be checking out iClever’s other models. Many other 3rd party keyboards gave me a mushy typing feel which I hate.
