Customer Ratings & Reviews

When using the mouse, it allows the screen to scroll up and down uncontrollably.

This is not a seamless experience when you set the mice for Windows and Mac simultaneously. Worst Product to go with.

This item did not work at all even after the computer guy came by to help us. Something is defective

The mouse signal keeps getting lost. I often have to wait 3-5 seconds for the mouse to reconnect with the computer.

Customer did not like it - clunky and hard to move around

Junk. Will not maintain a connection to a computer. Mac or PC

Not happy with it! Would not work. I waited to long to rerun to store.

I am a person who requires a mouse that can fill the entire hand otherwise, I develop hand cramps after some use. The Logitech triathlon is a perfect full-sized mouse with tons of useful features. The 3-device connectivity is perfect to easily switch between multiple devices. They scroll wheel has amazing hyper-fast scrolling and the gesture button is so useful. All in all, you are getting what you pay for.

Had this mouse for a couple of weeks and find it to be very comfortable for my large hands. It is an impressive mouse with the smooth scroll wheel, ability to change the shortcut buttons, and is very quiet. Like the Bluetooth feature. Traded in a 15-year-old mouse for Best Buy recycle program and got an extra 20% off the sale price. Thanks, BestBuy, for the great deal!

This mouse is very easy to connect to any laptop or desktop computer. You can customize the mouse just about any way you want using Logitech options download. I use two different computers so to have the ease of just switching between them with just a click of a button is just great! I have had the mouse for over a year and the original battery is still in it, it surprisingly lasts very long. It is very comfortable and it's a tech must have!

Mouse lasted one month then would not pair with any computer.

I've bought this mouse not once, but twice - I think you could guess what happened to the first from the title. What a delight this mouse has been to use. I switch between my work PC and my personal Mac quite often. Being able to seamlessly pair with and switch to multiple devices has been a dream. Having the option for a wireless USB dongle connection as well as Bluetooth has been fantastic - I even use this mouse for Samsung's DeX platform on my Note 20 Ultra from time to time! The buttons on this mouse are super satisfying - just the right amount of clicky, in my opinion. As with other Logitech mouse models, you can change from smooth to clicky scrolling with the press of a button, which has proven to be super useful for projects I've had to work on. The discreet thumb button is also very useful for switching between tabs. There is one downside that I've noticed - the sides tend to wear down with about a year to a year and a half of use. That's pretty normal, but I'll miss that soft matte finish on this wonderfully-shaped mouse. Overall, I love this thing. It's been excellent for my tiny hands.

The mere fact that I was able to pair it with my computer is enough for this computer ignorant 72 year old!

Its large but my hands are large so that is good. The only thing I don't like is the thumb click function on the side. I thought it would be great but I often trigger it without intending too. Caveat. That could be my meat hands instead of the mouse's fault.

Finally! I've been waiting for Logitech to release a solid multi-device mouse with the same quality as their dongled m510 (which has been my long-standing favorite). This new mouse is even more comfortable, and can use either the dongle OR bluetooth! Now I can free up a precious USB port on my laptop. Also, with multi-device, this means that I can press a button and switch between the 3 devices at my desk (laptop, phone, linux desktop). This is perfect! PLEASE, Best Buy, train your associates to know about multi-device equipment! Many of us are productivity-minded and have multiple devices being used at the same desk. I hate unplugging dongles or using separate mice for each device. THANK YOU for carrying these!

Shape feels excellent in the hand. I think feedback on the main buttons and the side buttons is great. There is a prominent switch for toggling between smooth and notchy scrolling- I'm a fan of the latter and so will never use the switch, but I guess someone may appreciate that. Far too new for me to comment on longevity, but it feels like it should be solid in use. Storing the dongle inside the base is a smart design touch that I wish had been done on the smaller Microsoft mice that I've had before. Ideal for a stationary workstation or limited travel. A bit bulky for on-the-go laptop use, would recommend a smaller shape or folding type for that.

LOVE the 3 device flexibility of this mouse. I have it connect to my home laptop, iPad, and work laptop. It's an accurate mouse with a good feeling trackwheel.

Feels very smooth even with no mousepad and has a great battery life as advertised. I think it's the best wireless mouse at this price. I wish it were just a tiny bit smaller and lighter but that's personal preference.

Works great. Using in Bluetooth mode with my 2019 MacBook Pro Intel based, which only has thunderbolt ports. Be sure to hold pairing button down when first using. Also works with my other two windows computer.

I love this mouse because it is very comfortable, accurate, and easy to use. I am thinking of getting more for the other computers in my home.
