The Canon r40 scanner works like a champ.

Horrible experience - after multiple hours through multiple customer service reps (over several weeks, given they take >1 week to reach back out), I found Canon no longer supports MacBook

With Canon, you get the Canon software AND TWAIN support, which means you can use anything!

Not only is the Canon ImageFORMULA R40 easy to use, it has a very small desk footprint.

However, Canon is mistaken: this scanner does not work with Big Sur, no matter what fixes one tries

At lower resolutions, I would say the Canon is almost twice as fast.

The Canon is MUCH cheaper.

Canon swears it works with Big Sur and has not even released an updated driver or software package for it

I finally found the section in the scanner software that allowed me to rotate a page that scanned in the wrong orientation (having it worked into a right mouse click with some other options would be useful Canon).

Canon has been totally non-responsive

At the end of the day, feels a bit clunky and mechanical b/c of the software.

It does take a bit of tweaking to get a setup that allows you to name the files the way you want as well as where you want them to scan to

Its annoying, but not as annoying as when it goes into sleep mode and starts FLASHING BLUE
