Brilliant for productivity!!! Ambidextrous without the drawbacks
Reviewed in Australia on 10 May 2019
Just got it today so can't comment on longevity, but it is brilliant for productivity (ie everything that isn't gaming - copy and paste, up and down volume, spreadsheets, word processing, all that stuff). 11 programable buttons that you can program to do just about anything productivity related. I use (&) a lot (and then fill in parameters) so I set it up so that at the press of a button, my email has (&) ready to be filled in. If you regularly drop a paragraph into a letter, set that up and at the click of a button, it would drop in. I will mess around with it and probably find something more useful to assign to the button, but for the moment that works for me.
Light weight mouse and all the buttons are light and easy to press and easy to distinguish from each other - even the ring finger and pinkie side buttons. I am a female with an average sized hand and find it on the largish size, but comfortable. Ambidextrous which I love as due to shoulder problems, I use both left and right hands equally throughout the day. It is very flat front to back. There are 5 available profiles - where you assign tasks to the buttons. I have set one up one profile for my right hand and a mirror image profile for my left hand. Let me assure you I am no computer scientist, but I literally had it up and running within minutes of opening. I cannot get it to connect to the Logitech Unifying Software as it comes with its own gaming dongle. No biggie, just connected the dongle to a USB-C dongle on my MacBook Pro and good to go.
Oh, if your left click button starts double clicking, google it (not YouTube) and tech writers have you covered (not a problem on this mouse, but previous Logitech mouse had the problem) I did something along the lines of going into accessibility and changing the cursor speed, worked just fine.
It is probably great for gaming too, but as I am all thumbs the gaming world is safe from me.
