Before that, there were two Apple wireless keyboards on the table. One was needed solely to switch the iMac to monitor mode, the second - for the main PC. Having bought this keyboard, I intended to use only one instead of two, but unfortunately the bluetooth often tends to fall off. Thus, as I had two keyboards on the table, they remained, besides, this one also became wired, which is very sad for me personally. I hope it will be possible to overcome the creak, I had to buy more lubricant. But in general, I really like the keyboard, it's nice to use!
