had(which is given to my dad then) from staples... just some trivial flaw like the off/on button does not perfectly showed by its red/green color

I bought one and it had a fatal flaw: the horizontal tracking was not very good

This mouse actually suffers from a fatal design flaw.

This could have been the perfect business mouse except for one FATAL flaw: the right button is so sensitive that I click it accidentally several times a minute, which totally blows my concentration

super hand fit and in all functions is as smoothly responsive as you could ever want, without being jerky.

I'm also confused as to why Logitech Options isn't compatible with this mouse

Although I've tried Logitech's $66 MX Master and a different, $12 laser mouse, I still prefer the M705 as of this writing
