Cons: I personally prefer a completely smooth scroll, but this mouse has has the type of scroll that's a bit stiff and bumps every time you scroll

The other thing is that the scrolling sometimes just stops working on browsers

My only complains are the lack of a on/off switch, which might be subject to individual use, and the bad scroll wheel that my piece has

The scrolling is also very erratic.

The scroll up, scroll down button broke after just 3 months, cant return it now

Scroll intermittently would not work several months after and the company replaced through a simple e-mail

If I switch to another tab, it works, if I reload the page, it works, but sometimes the scrolling just totally stops working

The scroll totally stops working

Soon after the rubber on the left side, where you support the thumb, began to get sticky and deteriorate, but well this did not matter, what I can not tolerate is that it has begun to fail the mouse scroll as it does very uncomfortable using the mouse in general

50 days of use and while I love it overall, the past 3 days I've noticed that scrolling via the scroll wheel has become erratic

When scrolling, it would randomly register the opposite direction making any system that incorporates the scroll wheel unreliable

I love the look and feel of this mouse, but it's just awful when scrolling

Secondly, the mouse scroll isn’t free-scrolling

The scrolling is terrible and doesn't work half the time

I liked the mouse for quite a long time until the scroll up and down function stopped working

If the scrolling becomes worse, I may have no choice but to look for another mouse, which is too bad as I do like this model.

However, the scrolling became terrible after 1 year of use

Additionally the scrolling doesn't work fully anymore and lags or goes the opposite direction randomly

Works on most surfaces, I use it on my bed and it works great!Clicking and scrolling

I bought this to replace one with a problematic scroll wheel

The scrolling isn't smooth and it lags and goes back and forth which is very annoying

After I used it for 2.5 months, the scroll doesn't work very well

I really like this mouse, but for some reason the one I received has a defective scroll wheel

The scrolling isn't smooth and it lags and goes back and forth which is very annoying

The scrolling is jumpy and inconsistent and even goes the opposite direction sometimes

Comparing the two, I like the scroll on this as it has better

After 6 months the scroll doesn't work properly and the piece of rubber that's glued on the side slides around so that glue gets all over my hand

I love the look and feel of this mouse, but it's just awful when scrolling

The scrolling no longer works

Unfortunately, the last time I bought from them, the mouse's vertical scroll was faulty in a way that made no sense

Then it will just stop scrolling at all, unless you refresh the page or move to another browser window

The scrolling is broken and won’t stop scrolling down

Now, the scroll on the mouse is not working

Cons: I personally prefer a completely smooth scroll, but this mouse has has the type of scroll that's a bit stiff and bumps every time you scroll

The scroll wheel it slow too - like 1,000 rows in excel in 8 minutes on the mouse

Broken scroll wheel (jumps up and down regardless of

if I had, I would have seen all the comments about how bad the scrolling is on this thing.

scrolling stopped working

This device is everything it promises - excellent design, ergonomic fit, delightful clicking action, and steady scrolling

Awesome precision, nice feel, good scroll wheel, and just the right buttons

Sometimes its fine, others scrolling down will scroll up and via versa.
