The concept is appealing, considering how fast the Apple wireless KB drains batteries.
But this one keeps dropping the Bluetooth connection, and Logitech doesn't seem to bother providing support or follow up.
On top, the first one I bought had a faulty Shift key, so I had it exchanged.
In summary, poor quality, useless (I reverted to my Apple KB), and with no support.
Simply put, don' t buy it.
PS. I gave 1 star as 0 star is not possible
