I am very pleased with my new keyboard (and mouse - MX Anywhere 2S). Both easily connected to my iPad, MacBook, and work PC. The keyboard is very comfortable to use. The battery has not needed recharging since the first day (it has been several weeks), and I use it for at least an hour or so daily.
This thing is AWFUL! The feel is great, and stays similar enough to the regular MX Keys to not be an issue. The battery life is a whole other issue. This thing is constantly turning on when no one is near it. Due to this the battery only lasts about two days no matter how much you are or are not using it. Not acceptable.
The connectivity is super fast and reliable with Mac. The membrane key worked better than expected, after moving from a mechanical keyboard. It is silent. Good options for the function button, although, I'd like a few more customization.
Lastly, I love the backlight feature. I turned off the auto-light. During the day I have the light all turned off, and at night I just tune it up to the first level and that's enough. It's been two weeks since last charge and battery is at 50%.
Downside is that you cannot charge/connect and use the keyboard. Not a biggy for my use case.
It is heavy due to extensive metal in the frame, but keys have the best feel of any keyboard I have used. Excellent battery life and reliable Bluetooth communications with my computers. I like it a lot
