Logitech Signature Comfort M840 L Wireless Mouse, Bluetooth Mouse with Silent Clicks, SmartWheel, Customizable Buttons, Off-white - PC, Mac - Optical

[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

[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.

[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

[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.

[This review was collected as part of a promotion.] The Logitech Signature Comfort Mouse discomfort in the palm of my hand. This mouse molds to my hand perfectly, making it easy to navigate without sore fingers and wrist. One amazing feature is the Bluetooth capability. It freeze up a USB port, allowing me the freedom to carry on other tasks and still utilize my mouse. It is battery operated so I have to remind myself to turn the mouse off using the switch on the bottom. This Logitech Signature Comfort Mouse is well worth the asking price so I can have pain-free computer access.

[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.

[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.

[This review was collected as part of a promotion.] Very comfortable and responsive, it comes with a battery included is AA batteries which that’s easy to replace, super cute is white and portable the design is also comfortable when I use it all day at work, the fact that is wireless is the best part user interface and is Bluetooth it doesn’t make that noise when I move it around.

[This review was collected as part of a promotion.] This is a nice mouse by Logitech. It is very light wieght. The clicks are also very silent. I have received in white color. Logitech brand products are nice in quality. I liked it and highly recommend it.

[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

[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!

[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

[This review was collected as part of a promotion.] This is very light weight! It’s pretty. Easy to connect to your Bluetooth device. The grip isn’t like the other Logitech units. Some may love it but I didn’t. There’s a button on top that I need an explanation on what it does…?

[This review was collected as part of a promotion.] Very comfortable to use! It's very smooth and very fast. I especially like the fact I can use it on multiple devices and that I can set up shortcuts with custom buttons.

[This review was collected as part of a promotion.] Logitech wireless mice stand out for their excellent value for money, durability, and precision; they are very easy to use and serve as a highly useful tool.

[This review was collected as part of a promotion.] I received this product from Influenster in return for an honest review. I’ve been using it for work for a few days now. At first it took some getting used to lol. The button and scroll are super sensitive and it’s a different shape than I’m used to. However, I quickly noticed it’s more comfortable for my hands and wrist! I really like it and it has now replaced my old mouse. Highly recommend! Easy to setup and connect to Bluetooth too.
