Do you already own a wired model O? This is just as good . Except now you have wire freedom. However there are some small differences.... il share them here . As for functionality of mouse and such, you can just read reviews online.
Ultra light even though it's internal battery power. But I weighted them and wireless O is 74g and wired O is 72g. Even if advertised as 69g for both wireless and wired , that's just not true unless my scale is wrong ?
Note that your must install the wireless specific version of the Modelo software. Uninstall existing glorious software first. Else there will be conflicts. It's too bad that one software doesn't figure out the decide and work for alll glorious mice. Logitech mice and keyboards have one software that supports all Logitech products.
As for usage... Wireless switches are just the same as wired . However you must know that if you have broken in a glorious mouse, the switches become a lot looser. So then comparing a brand new wireless switch with a broken in switch , you'll always fine the new one stiffer. It takes time to break it in so be aware.
Battery life is ok. Not a forte for this product but it's expected . Depends on your usage and Hz you use. But approximately 8 to 10h usage. ..
One last point, I find the mouse weighting slightly different than wired mouse. Likely due to the internal battery. So you may or may not like the wireless . The feel isn't identical due to weighting.
