Large, symmetrical, wireless mouse for big hands?

[qwsazx]

Hi all.
I'm looking a replacement for Logitech M510 mouse. Preferred classic design for office use (no need to go for gaming device). Symmetrical or for left-handed guy with large hands (24 cm / 11 cm, according to measure method shown here:

Grip type (palm, finger tip etc.) doesn't really matter.

So the perfect mouse should have at least 12 cm length (like M510), preferrably even more. It can be heavy one. Any suggestions please? I tried to find anything on my own, but failed. There are mostly small mice for laptops on the market now.

Thank you in advance.

I don't want another M510, as this was overall good mouse but with one really annoying feature - going to sleep after 0.5 sec. of inactivity, waking it up requires some dynamic movement or clicking buttons. Sometimes it caused unwanted behavior like closing windows etc. :/ So, no more M510.

I would have recommended the gigabyte m6800 for comfort (NOT a gaming mouse) but it's wired. For wireless you might need to look at ergo mice, which generally means expensive and mediocre sensor.
Microsoft makes some decent upright mice, do you like those?

Seems interesting, will look for it. I can live with wired one if it's worth to use

Yes, I've examined Sculpt Comfort and Arc Touch. I don't feel convinced though.

Thank your for your help.
