Too many options to manage my device. My keyboard uses the original Mouse and Keyboard Settings, my travel mouse use LogiOptions and now my desktop mouse uses Options+. Either make new stuff work in the old, or keep supporting old stuff in the new. I'm tired of having to load and try 3 different s/w just to make one change. And the whole, use the web to control which BT devices connect to my local machine is so overkill. I hate it. Trust me, as I have to replace things, I will start to look for a new vendor. 30+ years I've been a Logitech user, but I think the time has come to end this relationship.
