I bought this because I needed a new keyboard. It's appearance and build are solid, near-apple quality, and the keys are almost identical to an Apple keyboard and it worked great, but I'm just not sure I get the concept of a wireless keyboard. A keyboard just sits on your desk next to your computer... why does a wire matter? Not having a wire creates its own issues... now the keyboard has to be powered somehow, so Logitech has wisely included solar panels on it to charge it. Nice idea, but now I have to turn on a light to use my keyboard if the room is kind of dim. Also, I'm losing the 2 USB ports which are normally on an Apple keyboard (the keyboard being wireless doesn't save a port because it needs a USB dongle to work). In addition, they suggest you install an app to monitor the keyboard charge level, an app which has terrible reviews in the App Store... search for it if you want to see. So, in order to eliminate one wire, the keyboard complexity is increased with the app and solar panels. It just makes no sense to me... just keep the wire! In addition, I was having computer issues so I had to boot from a DVD... holding down "C" while booting didn't work with this keyboard, so I ended up having to set up the DVD as a startup disk, which worked, but is a poor solution. After trying to restore my system from a backup, I was faced with a kernel panic. Suddenly there was no way to designate a startup disk or boot from the DVD, so I had to get my Apple "wired" keyboard and hook it up just so I could boot from the DVD! I'm pretty sure that was another problem caused by the wireless aspect.
I'd not buy another one; Keys have nice feedback and action; my kingdom for backlighting.
Works fine enough but it's been about 6 months and now it's being a bit of a princess about battery power and available light. It takes an oddly long time to recharge even in direct sunlight. What are powering up here? Once it hits about 5%, it pretty much punts. A little (I mean occasional) lag but not enough to consider it a liability. Does NOT have a CAPS LOCK indicator or light or anything that give you feedback. Had to spend a buck at the AppStore. It's not the money, it's the fact that such an elementary item was omitted. Frustrating and finicky control panel.
It's good at best. But let's be honest, it's a keyboard.
