Many mice offer very basic functionality: left click, right click, scroll wheel and not much more. Others have an array of programmable buttons, premium sensor specs, USB-C charging, and other features for power users. But what if you don’t need that extreme level of functionality, but also don’t want something cheap and bare-bones?
Released last week, the Logitech Signature M650 Wireless Mouse is a mid-range device that supports Windows, macOS, Linux, Chrome OS, iPadOS, and Android. It doesn’t have the most advanced features, but it isn’t simple either. And by skipping some add-ons, such as multiple Bluetooth profiles, the mouse can keep an affordable price of $40.
Logitech’s latest wireless mouse also comes in three different versions: a standard size, a large size, and a large left-handed version, so there’s something for everyone unless you have a smaller left hand.
Different hands and sizes
Logitech makes it easy to determine which version is best for you. Those with small to medium hands, measuring up to 7.5 inches, should get the standard M650, while those with hands longer than 7.5 inches should opt for the M650 L.
If you have small hands and want a comparable wireless mouse, there are smaller options, such as the Razer Pro Click Mini (3.9 × 2.5 × 1.3 inches, 3.1 ounces with one battery).
The medium version is 4.22 × 2.43 × 1.49 inches and 3.57 ounces. That makes it a bit smaller in length and width (but noticeably heavier) than Logitech’s Pop Mouse (4.5 x 2.6 x 1.4 inches and 2.9 ounces), another Logitech wireless mouse with a suggested retail price. from $40.
The large M650 (4.65 × 2.58 × 1.63 inches, 3.92 ounces) is 10.19 percent longer and 9.8 percent heavier than the stock version I tested. That’s pretty big for a wireless productivity mouse.
It’s even bigger than the Corsair Katar Pro wireless gaming mouse ($40 MSRP), which measures 4.56 × 2.53 × 1.49 inches and weighs 3.39 ounces. However, there are larger wireless mice, including some from Logitech. The similarly shaped and cheaper Logitech M510 (4.72 × 2.56 × 1.6 inches, 4.55 ounces) is so heavy it feels clunky.
There is a left-handed version of the M650 – the side buttons are on the right side of the mouse – but it’s only available in the large size. Wireless left-handed mice are hard to find — there’s the $100 Logitech G903, plus less traditional mice, like ergonomic mice and Microsoft’s Surface Arc. But for a regular wireless mouse aimed at productivity, this left-handed option is a rare treat.
With so many options, it’s easier for people to find a good fit, especially if they don’t have any preferences in their mouse form factor yet. There are mice that go to extremes with resizing, but the M650 should offer plenty of options for most people.
According to Logitech’s chart, I have a medium hand. My typical claw grip felt good with the M650, as my thumb and ring and pinky fingers found strong grip on the textured sides of the mouse. Meanwhile, my thumb was able to move up almost effortlessly and activate both side buttons. My index and middle fingers naturally fit into the downward slope of the primary buttons, but keeping them in my preferred position for quick clicks required more effort to keep my hand from sliding down.
I wasn’t so inclined to use my secondary grip type, a palm grip, on the M650 due to its shorter length. My index and middle fingers hung significantly over the top edge with a palm grip, making navigating the left and right clicks more difficult. But the mouse’s large hump helped with comfort.
