I love this mouse... or at least the idea of this mouse. The "Logtiech Options" software is super buggy and renders the mouse, well... useless... constantly dropping bluetooth connections. I've verified this on a windows 10 machine and a 2015 macbook and even tried older versions of the software on each. Uninstall the "logitech options" software and the mouse works perfect!... but you lose all the special functions/customization... and end up with... well... a very expensive normal mouse... I see many complaints of this very same issue all over the Logitech boards. Logitech needs to get this addressed ASAP. Until then... 1 star for this normal (very disappointing) mouse. I'll hold on to it for now to see if this gets fixed... i want to like it, i really do want to like it.
