mode it automatically free spins until it slows down and then goes back to ratchet.

The free spinning "hyper fast" scroll wheel confused me for a bit, but after I got used to it, I love it and bought a 2nd one

Also it has this cam feature where if you scroll the wheel hard, it goes into a free spin and out of a ratchet mode.

- lack of acceleration control is appalling (e.g. you can’t disable it at all) - scroll wheel keeps slightly moving all the time in the free spin mode, very annoying - side scroll is not as comfortable as I expectedI wanted a mouse that would behave exactly the same in Windows and Mac

If you try to move the scroll wheel quickly it disengages the mechanism and becomes a free spinning wheel

The clutch allows it, if you have it setup to do so...if you flick the scroll wheel it will free spin until it slows and re-engages the click-scroll

Wheel Scrolling can shift from Free-Spin to click-spin

Terrific Logitech mouse software- Free spin and ratchet scroll

Feels very nice in hand, responsive, good clicking, free spinning wheel is excellent, love the color.

I am a photographer and designer and having free spin is great for changing brush sizes, brush hardness, opacity, and other options in photo editing programs

The Scroll Wheel - The scroll wheel has an automatic selection between fast free spinning and slow click modes

Mouse also has a button below the scroll wheel that either gives you the normal detent scroll or unlocks the wheel so it free-spins for hyper scroll.

The free-spin "hyper-fast" scroll wheel has changed my life

Didn’t have issues with that part - configurabikity is great - gestures are a nice touch, although not sure long term - nifty free spin scroll when functionCons - very heavy for a mouse

The nicest thing about this "super mouse" is the scroll wheel, which is solid and gives you a choice of ratcheted or free-spinning

The clutch allows it, if you have it setup to do so...if you flick the scroll wheel it will free spin until it slows and re-engages the click-scroll

I leave the scrolling as Rachet so that it's more precise, the free spin is a bit too imprecise for me.

In free-spinning mode, it coast for a long time before the flywheel action drops into a notch that stops it from spinning

When you click the center button, the mouse releases the friction of the mouse and allows it to free spin

Free Spin, no ratchet mode.

Pros:--The scroll wheel can switch between ratcheting and free-spinning.

The wheel has two settings: the normal settings which has some light clicks when used and a speed scroll setting which is just a free spin for very fast spinning.

I love that when I need to scroll down a lot, if I spin the mouse wheel fast enough it will go into "Free-spin" mode until it slows down

and I really like the weighted free-spinning wheel.

mode it automatically free spins until it slows down and then goes back to ratchet.

The free spinning "hyper fast" scroll wheel confused me for a bit, but after I got used to it, I love it and bought a 2nd one

Also, the normal wheel scroll (before it goes into free spin) is kinda loud and when you free

The extreme flexibility of being able to configure the buttons for your specific needs is a great benefit.4- The button on top, directly behind the wheel, changes the functionality of the wheel from individual clicks to continuous silent spin

Speaking of that, I love the free spin mechanism

The free spin button is something unique that I have not seen on any other mouse

The wheel, within a week, wouldn't go back to the normal setting and was stuck on the fast spin setting.

The mouse is in a perpetual free-spin mode

The mouse wheel has free spin mode, and ratchet mode (selectable with a little toggle button above the wheel).

One when the freewheel is set in free-spin mode (no ratchet-effect like traditional mouses) web pages would jump back the opposite direction when scrolling down (would jump upwareds) intermittently when I stopped spinning the mouse wheel down
