I can testify to both of these statements with regard to Logitech.
I’ve had 4 high-end Logitech’s in a row fail due to the double-clicking thing after roughly 6 months each. Three of those four were brand new replacements Logitech sent me under warranty, and they did not require me to return my faulty ones.
But after the fourth went bad, I gave up on them. I switched to a Corsair M60 five years ago, and have had not one single problem with it. Totally in love with the thing, although their newer versions (like the Corsair M65 Pro) are probably improved, although I can’t see how, because to my mind, the Corsair M60 is perfect, though apparently no longer available.
Hmm. I see the newer M65 Pro is optical, while the M60 is laser. The plain M65 (non-pro) is also laser. I wonder why that is. Is optical better in some way?
