I'm sad to report I'm not hear to leave and outstanding positive review on this keyboard. When I purchased it in October I was thrilled with the price, design, and solar concept. I recently purchased a 34" monitor for my office and decided to use my personal mac as my work computer moving forward.
At first, the keyboard was amazing. The disclaimer says you have to plug the receiver directly into the computer, no adapter, however the new Macbook pro only has USB-C ports so obviously it had to be connected through an adapter. (Strange seeing as how Logitech claims this keyboard is designed specifically for Mac, I personally believe the disclaimer saying it can't be connected through an adapter is something for Logitech to use as an excuse when the keyboard begins malfunctioning - but hey, that's just me)
The 1st few months of use - zero problems. The keyboard performed exceptionally well even though I defied the rules and connected it through an adapter. It perfectly matched my white Samsung 34" monitor, and took up very little room on my desk. However, after about month 2, the connectivity issues began. Every once in a while there would be a lag, or the keyboard would respond for a few seconds. I would turn it off for a few seconds, turn it back on, and we were good to go. Yes, it was fully solar charged.
As of this month (month 4) they keyboard has begun causing problems for me daily. Unresponsive to key strokes, hitting the batter test button one second will give me a red light, the next second it will give me a green. I'm having to repetitively hit keys to get them to type and when they finally do it leaves me with an entire line of the same letter. I've tried computer restarts, plugging the receiver into different adapters, as well as different ports on each adapter, but the problem is clearly within the keyboard itself.
I can't say I hate it, because I very much enjoy this keyboard when it actually functions. I like that I have the built in number pad, and for whatever reason it just seems more comfortable to use than apple's bluetooth keyboard.
As of now, I have no intentions to replace it. My hope is that whenever the connectivity issues occur they will continue to straighten out quickly. My fear, however, is that the performance will continue to diminish to the point I will end up having to replace.
