All of the buttons have an easy click to them in which you don't have to press hard to perform you actions, except for 11, 12, and 13, these you have to press just a little more until you get used to it.3

In terms of build quality, I was met with a solid rubberized feel with sturdy and reliable clicks

Mouse 11 and Mouse 12 are too tough for me, but for some it may be fine and prevents accidental clicks

But now after a mere 7 months the mouse has quit on me, the right click no longer registers

But it is way to heavy and other than the left/right click buttons which feel really good the rest require way to much pressure to activate

Same goes for the right click side single button

he scroll wheel), and 13 on the left side of the right click button (next to the scroll wheel) rather than where they are now

My favorite buttons are the bottom ones, which are stiff enough for extra thumb support without the fear of accidental clicking

You can easily be pressing and holding down on your right click button and roll your finger over and press the custom button on that side and never lose your right click hold

You get 2 buttons on your index finger next to the left click, one button at your right click finger and a VERY sturdy tilt scroll wheel mouse with a down click as well

3 months after purchase, it started to be non-responsive about 1/20-30 clicks (on various buttons)
