design and functionality
Aside from the Apple Magic Mouse that comes with several iMacs I’ve owned, I’ve almost exclusively used Logitech mice. And after years of various mice, I have to say right away that Logitech really nailed it with their M650 Signature mouse. Naturally, when designing a device, consider the multitude of hand sizes, whether the user is left- or right-handed, and delve into the color options. Logitech has taken a smart approach by creating 3 categories of options and allowing the user to customize their choice. Left or right? Big or small hands? What is your favorite color? And you like to use a low energy USB dongle or old Bluetooth? The latter is a trick question, as both are available regardless of hand size or configuration. I got the large option for this review and it fits me like a glove. The sides of the mouse are covered in a grippy rubber surface along with multiple ridges for better traction. The side buttons rest right on my thumb and are immediately accessible. Everything feels “just right,” no surface seams that subtly cut into your hand all day, and no awkward angles. Just nice ergonomic curves. Maybe I got lucky and got a perfect fit with this mouse. Naturally, there are left and right mouse buttons in the standard configuration. These are also a beautiful shape. There’s a subtle lip on the top edge of the buttons, giving your fingers a clue as to where the end of the mouse is.
The buttons are almost silent. It’s great. I love him. I don’t know why, but I half expected not to hear a click as audible feedback, but there is enough tactile feedback to register it without the noise. Smashed keyboards don’t bother me, but I’ve learned there’s no reason to listen to a hollow mouse click a million times a day. In a room with average ambient noise, you’d barely hear the M650 click next to your head. Centered between the buttons is a nicely textured scroll wheel. I think this is the first Logitech mouse I’ve used with its SmartWheel scroll wheel, but I like it. It is very easy to turn; reminds me of the smoothness of a weighted scroll wheel mounted on a bearing. There are subtle tactile bumps when scrolling which is nice too, just enough to give feedback. There’s a bit of extra tech in this SmartWheel, you can give it a little nudge and the scrollbar responds in the same way, while giving the wheel a good spin is enough to propel a website all the way to the footer. The SmartWheel can be pressed down to use it as a fifth mouse button. The function of all buttons can be customized through the Logitech software. Like buttons, it’s also extremely quiet. How many times have you been in an office or waiting room and heard “ooh, let me see here” and heard a mouse wheel squeal like a baseball card hitting the spokes of a bicycle? It’s a good scroll wheel. Sorry. Smart wheel. Flipping the mouse over reveals an on/off switch, pairing button, and battery cover. Inside this cover is a slot for 1 AA battery (which is supposed to power the mouse for up to 2 years ) and the “Logi Bolt” USB receiver.
