I believe this review incorrectly states that the Logitech MX Master 3 has an ambidextrous design. The Office Depot description notes that it is for 'right handed' use. Just as seen with the Logitech MX Vertical, these recent interesting designs from Logitech are only available in right handed models. I can only assume that the population blessed with dominant left hands are not of a sufficient number to justify design and production of left handed versions. Not a big deal as I've always found Logitech's actual ambidextrous products to be excellent products.
Hi Marti. You're correct: the MX Master 3 is right-handed only. Long story short, we were adding pros and cons from a different document, and they got mixed up with another device. I've added the proper ones here, and the story should now be accurate.
