Great everyday mouse
on April 3, 2026

[This review was collected as part of a promotion.] The new Logitech signature comfort M840L is a super solid everyday mouse. The silent, clicks and smooth scrolling, make it feel almost ghostly quiet, which is great for shared spaces. You also get two side buttons that you can customize through the Logi app for Windows or MacOS, which is perfect for shortcuts. And one of the best features is the ability to connect up to three devices over Bluetooth and switch between them instantly with the push of a button on the bottom. I’m using it with my Windows work machine during the day and then at the end of the day I easily switch it to my Mac with the push of a single button. Couldn’t be simpler. Another great mouse from Logitech. It’s simple, all day use comfortable, and surprisingly versatile.

Nice mouse!

[This review was collected as part of a promotion.] Overall a really great mouse - soft click is important to me, but if you like loud clicks you won’t like this one.
Feels bigger than a standard mouse to me, but is still quite comfortable to use.
The only reason I took one star off is because it is battery-powered rather than rechargeable.

Thoughtfully Designed Mouse
on March 31, 2026

[This review was collected as part of a promotion.] Logitech's M840L mouse is one of the most effective multipurpose mice I have used. It's larger, ergonomic shape supports and cradles the back of my palm more than any previous mouse I've owned. It's lightweight, but feels like solid. It feels like care and thought was put into the design and components, rather than cheap materials. The bottom outer half of the mouse is made of a rubber-type grip material that helps you maintain a secure grip on the mouse when in use. It's silent touch buttons are true to their word, while still giving solid feedback to your fingers. The feature I am most impressed with is the capability to switch between devices with ease. You can link up to 3 bluetooth devices to the mouse and with the click of a button on the bottom, swap between them. The sync takes anywhere from 3 - 5 seconds for me and I couldn't be more impressed. Also, when you lift up the mouse to look at the bottom, the light above the Bluetooth swap button lights up to signal which device you're connected to. It's a small feature, but a very thoughtful one and definitely puts this mouse into the 5/5 rating for me

Works great

[This review was collected as part of a promotion.] I love this. I love the soft touch of it and the silent click. The shape of it is nice but is a little big for my hand. It was easy to connect to my computer and I love that you can connect to multiple computers.

[This review was collected as part of a promotion.] I am so glad I got this Logitech comfort computer mouse. It is so comfortable to use even after using for hours upon hours in the office. You will not want to go back to using a traditional mouse once your hands feel this one!

Comfortable Mouse with Useful Everyday Features
on March 27, 2026
Posted by: RawadB
[This review was collected as part of a promotion.] I tried the Logitech signature M650 L wireless mouse, and it feels comfortable for daily use specially if you have a larger hands, the size is good and it fit naturally in my hand, making it easy to use for longer periods. In the term of functionality it works smoothly with responsive tracking and scrolling the features like quit clicks and simple controls are helpful without beginning complicated. The power is efficient since it runs on a battery that lasts long time. Overall durability seems solid and it feels like it can handle regular use without issues. Also worst mentioning that I like the click mechanism in it where it doesn’t produce a lot noise
