What has happened to Logitech?! You used to make great quality products (still remember my first iPod dock) and now all you do is to spew up as much as you can and not even bother to run UAT on it before shipping out. And don't get me started on Options+. Oh my god, if I had to pay for this, I would have requested a full refund a long time ago. Nothing but problems with the MX range of keyboards and it hasn't helped that consumers have had to rely on Options+ to get any kind of use out of them. Here I am typing in the dark and my keys are not lighting up (happy that I am a pretty good touch typist). Turn the auto off and the keys never turn off regardless of the light in the room and then the battery goes after a couple of days. If it wasn't for the fact that I find Flow (when it works!!!) extremely useful, I would definitely look for alternative brands
