The top mouse wheel has 2 modes. ① clicky. ② free spin.

It automatically switch from clicky to free spin, when you flick it fast.

You can turn this auto-switch off by pressing the button on top of the mouse, to make it stay in spin mode or clicky mode.

Thumb Wheel

Thumb Wheel. This lets you scroll horizontally. But, how often do you need to do that?

Better, is to set it to {switch tabs, switch apps, switch windows}. That's extremely useful.

The 2 buttons behind the thumb wheel is by default browser forward/backward page. They are kinda awkward to use.

Potential Problems

amazon reviewers point out the following potential problems.

• The scroll wheel notched/spin may break. Many said that it becomes just spin, impossible to set to notched mode.

• For some unit, the wheel is not evenly weighted or such, so that when you leave finger off the wheel, it may rock a bit, causing page to move.

• bluetooth does not work well on the Mac.

• The thumb wheel may be too sensitive.

So, i'm not sure about this mouse overall. If a mouse is great in every way, except 1 in 10 it's defective, then it's not good.


for wireless, compare Logitech G602 Wireless Gaming Mouse. It has lots buttons, but no spin-wheel nor thumb wheel.

this Logitech G700s Mouse Review, also wireless, but battery lasts only a few days. But has spin-wheel.
