What settings are you referring to specifically? I still feel I’m slower using it versus a regular smaller mouse. I have been using it for 3 days straight. I feel I’m more efficient using it work time but I will try my former Asus mouse to see if the difference is still as big.
have you installed Logitech options+ (downloaded from Logitech website) - it has all the customisation features, and you're missing out on all the benefits of this mouse if you haven't
you can download custom mouse configurations for every app program (ie have the scroll wheel scroll up and down in excel, and zoom in and out in your browser and it automatically switches settings between programs without you having to do anything). You can also customise these yourself ie have the scroll wheel increase/decrease the volume if you so choose
there's also Logitech flow - you can connect two laptops and copy and paste from one to another - I use a windows laptop for work, and Mac from home and can do this between my work and personal computers. you can work across both devices as well, when connected (with the same mouse)
lastly - RE comfort - this mouse has to be held differently. further back, with your palm closer to the desk. I'm a petite female with small hands and don't have any issues at all holding this mouse. in fact, had carpel tunnel prior to using this which is now gone
I don't have any lag on either of my computers, but if you do, use the Logi bolt usb adapter with it, and that will dissipate any lag issues you have.
Highly recommend giving this mouse a proper try - it's AMAZING!! (I have 3 of them - 1 for work, 1 for home, and one in a travel case for being out and about)
on another note - the Logitech Mx Keys keyboard also has the keyboard customisations, backlight, works with Logitech flow using keyboard shortcuts, and can switch between 3 devices as well. it's a winning combo with the mx master 3s!!
