Buttons still in good place—identical to Master MX.
This mouse has 7 progammable buttons: left click right click scroll wheel click (scroll wheel) behind scroll wheel button 2 button on the side (side scroll wheel) and under thumb button The first thing I love about this mouse is the position of the buttons. The side scroll wheel, the thumb buttons—1 below, 2 on the side are angled so you can feel which is which are great. The orginal MX Master had this. They changed the layout of the Mx Master 3. They moved the bottom button to the front of the side, so it’s harder to reach in a gaming emergency situation. (I play a retro MMO RPG called Clan Lord, and the bottom button is my chain button.) With the button below the thumb, I don’t have to change my grip. With the MX Master 3 the forward further away from the thumb, which requires you to change your grip. The result is sometimes to fall while changing your grip. So, the MX 3 is a no go, the MX 2 is just right. I have 2 other mice, one an 11 button wireless, 502 Lightspeed Logitech, and a portable Razer, small mouse. While the MX Master 2 is less than the Lightspeed, the light speed retail price is almost twice the price (retail) than the MX 2. What else is good/great about this mouse? The all buttons are programmable with Logitech’s GHub software. The GHub can also configure other Logitech mice, and keyboards. It is also really easy to map a button. You simply select the button you want in a graphical display of the mouse. Click in the mapped window next to the button, and then press whatever key you want or other behavior from a pull down menu. The biggest plus is you can have different button mapping for each application, besides the default mapping you set. This is a HUGE plus. The next plus is the scroll wheel. if you don’t map the button behind the scroll wheel, then pressing it switched between ratcheted scrolling where the wheel clicks, to smooth scrolling that you can free spin and keeps going after you spill it to quickly scroll a window a lot further. The Next plus is the Side Scroll wheel. It is ratcheted, and by default it switches between pages if you don’t reprogram it. I remapped it to switch between chosen morphs (in CL) using 2 Fkeys as the equivalent buttons. The side scroll wheel by default switches between pages, and window views (what ever sights you visited). This could potentially be a problem, but luckily the side scroll wheel is out of the way of your thumb. So you have to raise your thumb to touch it. (In this case that's good, and you don’t have to change your grip much [at all really] compared to a MX 3's forward button.) Okay so how is the mouse move? Smooth, accurate. It also works on glass surfaces. The last thing is you can switch between which up to 3 computers by pressing a button on the underside. To program it you just hold down the button, then connect to which computer you want it to control. Bottom Line: This mouse is pretty awesome. Less buttons than some gaming mice, but a good number of them (7 +2 wheels). It is accurate, has good battery life, its buttons work and easy to program, looks good! I would buy this again.
