Yes, it's very quiet. I was worried about the roller being really loud and 'clicky' but it's silent!
I would recommend this to a friend!
Response from LogitechBy Logitech, October 16, 2026
The scroll wheel has passed your quietness test! We’re glad the Signature Comfort M840 L delivers the peaceful experience you wanted. It’s nice when a detail you were unsure about turns out to suit you so well. Thanks for letting us know!

Amazing🫶🏻

[This review was collected as part of a promotion.] The Logitech Signature Comfort M840L feels surprisingly premium for a productivity-focused mouse. The build quality is solid with a well-balanced weight and a contoured shape that fits comfortably in larger hands, making long work sessions effortless. The plastic doesn’t feel cheap, and overall durability is exactly what you’d expect from Logitech’s Signature line.
Noise is one of its strongest points. Thanks to SilentTouch-style switches, clicks are very quiet—almost muted—so it’s perfect for shared spaces, late-night work, or calls. You still get tactile feedback, just without the annoying sharp click sound.
Performance is smooth and reliable. The optical sensor tracks accurately across most surfaces, and the SmartWheel scrolling is a highlight—it switches between precise and fast scrolling seamlessly, which is great for both detailed work and long documents. It’s not a gaming mouse, but for everyday productivity, it performs consistently well.
The learning curve is minimal. It’s basically plug-and-play, and even if you use Logitech’s software for customization, everything is intuitive. You can start using it comfortably within minutes, even if you’re not tech-savvy.
Assembly is nonexistent—just connect it (wired or wireless depending on version) and it works immediately. No complicated setup, no frustration.
Overall, it’s a very well-rounded mouse that prioritizes comfort, quiet operation, and reliability over flashy features—and it absolutely delivers on that.

[This review was collected as part of a promotion.] I received Logitech Signature Comfort M840 L complimentary in exchange for my honest review.
The set up is easy using Bluetooth with my MacBook.
I loved the design and the quality of the materials. It provides good support and is very comfortable for my palm. I also appreciate the silent clicks. It just feels smoother experience overall! Great product.

[This review was collected as part of a promotion.] I love how it’s tailored for comfort with a soft rubber grip and contoured shape. It offers wireless connectivity using Bluetooth, features silent clicks which is great to reduce noise, and the side buttons are customizable which is a plus

Works great on phone and computer

[This review was collected as part of a promotion.] This mouse glides like butter and is so quiet. The side have a soft rubber on them and is contoured nice that my hands dont cramp while using it. I have smaller hands and it fits nicely. Its super easy to connect. It worked with my android phone and my pc. Your computer needs to have Bluetooth as this doesnt have a dongle. I have had no issues switching between devices, you can have up to three connected and the button to switch is on the bottom. I havent noticed any lag either. Overall this is a really comfortable mouse that's easy to connect and isn't too big.

Comfortable inconvenient, ideal for those who work

[This review was collected as part of a promotion.] I fell in love with this mouse as soon as I got it because it was easy to set up. There was no learning curve and it connected automatically to my laptop. I didn’t have to do any kind of troubleshooting because everything was so straightforward. It’s strong and durable and it’s easy to maintain. I do recommend this for those who are tied to a computer for a long in those who like convenience

Whisper Quiet Comfort
on April 17, 2026
Posted by: NicoleK
[This review was collected as part of a promotion.] The Logitech Signature Comfort M84OL is my new favorite mouse. My hand cups the mouse comfortably, and it is very easy to use. This could be comfortable for someone who works at a computer all day. I enjoy the side grips for ease of use and comfort. The Logitech Signature Comfort M84OL mouse is so quiet. I didn’t realize how loud the clicking is on my previous mouse until I used it again after the Signature Comfort. I never want to hear that loud, distracting clicking noise again. One feature I really appreciate is the buttons on the thumb side that let you click back and forth between the previous and current web pages. I am very happy with the Logitech Signature Comfort M84OL.
