Customer Ratings & Reviews

Great mouse to use with multiple units (I use it with 2 windows and 1 apple). Easy to program and switch between laptops when using multiple units. Size is just right for me. Little or no delay.

Amazing ergonomics and reliability for the price. I bought two. One for work and for home.

Offering great grip, smooth movement, and excellent traction on the surface, the value for money is outstanding. It’s slightly smaller than a full-size mouse, but considering its performance and versatility for both desktop and laptop use, the price is nearly perfect — an excellent mouse overall.

Connects seamlessly between devices, custom button mapping is helpful especially custom mapping profiles for different applications. Long battery life, and comfortable to use for long periods of time. For the price I don’t think there’s a better everyday mouse.

I use this mouse with the multidevice keyboard and it works perfectly. Switching devices is done by pressing a button with three number indicators. Simple to use. A plus is that it can be pared with bluetooth or using the Logitech Unifying Receiver.

I love the size of this mouse and use it all the time on my laptop. Works great wirelessly so no cords to tangle and mess with. Responsive and fast. A little on the large size for travel but with my larger hands it works for me.

This wireless optical mouse is great. It much easier to use than the wired mouse. I don’t have to worry about the cord tangling up with any other device's cord. The wireless mouse also works flawlessly no jerky motions like with my old wired mouse. Would recommend the to anyone looking to ditch the old fashion wire mouse and upgrade to a wireless optical mouse.

Considered buying a new iMac for the screen space, but came up with a better solution for multi-laptop family. Long story short, kid uses a Chromebook for school, wife has PC for work, and I have an old MBP for general use. Instead of buying a new machine and putting the laptops in a drawer to never be seen again, I purchased this mouse (and multi user keyboard) and large monitor to give us many more options. Once the mouse is initially set up/paired, which was super easy, you only have to press a button to switch to the desired device you want to use it with. No re-pairing and instant connection. It just works. Highly recommended if you are running multiple Bluetooth connections and don’t want to have to re-pair all of the time.

The triathlon is a great mouse because it seamlessly connects between three different devices. I use it for my MacBook, a windows computer, and my lab computer. It's great that I can so easily use it for all three without repairing every time. The bluetooth capability is really great, and the ability to use the included receiver is great when you use a really old device without bluetooth. Solid feel and nice materials too. The option to have a "clicky" or smooth scroll wheel is great when browsing websites or super long articles or documents. You can scroll precisely or line by line with the option. Make sure to download the Logi Options app to make full use of all of the customizable buttons. Really works great to optimize your workflow.

I bought it to use with 3 computers without having to use 3 mice. It pairs up very easily with each computer and has a convenient button to switch computers. I often have a Windows 10 laptop and a Chromebook at hand and I can now switch between them without keeping track of which mouse is for which computer. Logitech mentions a speed mode for moving through long documents. This is implemented by having a push button above the scroll wheel that disengages the ratchet and lets the scroll wheel spin freely. You then re-engage the ratchet when near the desired area of the document you are on. It is heavier than low-cost mice and I suppose there is an ergonomic reason for that. Maybe it keeps it more stable. In any case, it is easy to get used to. I use it without the optional (free) software package and it operates as expected with all of my computers.

This mouse is pretty insane given the feature capabilities but still offer a simple user experience. Even at an entry level perspective the price is a great value for something you can later customize and change to personal needs. At a consumer standpoint, it's plug and play on Android, Windows and Chrome OS. Bluetooth pairing is easy and smartphone friendly or the USB adapter with any compatible ports. Very excited to test more of the customization options that compliment Adobe products (Premiere Pro, Photoshop, etc.) and will update review after I've had more experiences with that capability.

Nice little mouse that does everything its supposed to do. Tracks well, fits nicely in your palm and has good scrolling. However the button next to the thumb is next to useless. I end up accidentally clicking it once in a while and its annoying. Otherwise would definitely recommend.

Mouse is great and easy to use on my MacBook Pro. I use it everyday as a college student and so far it has never failed me. Battery life is very good on it and the bluetooth connection is excellent.

Work so good, very easy to connect and use. Stays at 100 % charge for a very long time. love it Thank you

I've been using this mouse for about a month now. It's a pretty great mouse. The size is a nice medium I would say. It feels comfortable in my hand with a nice contour shape. Bluetooth seems pretty reliable so far. It also can connect via very tiny dongle if your computer doesn't have Bluetooth available. The buttons are nice. I didn't even realize it has a hidden button under the thumb groove. Learned this when I pressed it by accident. I use it on macOS with Better touch tool and it's pretty great. I got it on sale for around $37 and for that price it's pretty great.

This I believe is the update for the Logitech M705 Marathon Mouse, which had an 18 month lifespan on 2 AA batteries, this has a supposed 3 year lifespan on ONE AA battery! Forgive me if my numbers are off a bit but this is what I read some time ago. Compared to the Marathon Mouse which I'm upgrading from, this has a very similar feel, very ergonomic and decent size.. similar buttons, maybe one additional actually, and a new pairing button to connect the mouse to up to 3 separate devices and switch on the fly. Tracking is great and the software allows for many customization options. Highly recommend this mouse to anyone that actually needs to be using a mouse and not a touchpad, and is not exactly willing to pay $60+ for their MX Master series, which is what I really consider the best available.

This is a great mouse, a little bit to small to my hand but it is okay. It is very precise and have option for scrolling (fast and slow). Also 3 customizable buttons than maily works on internet (back, forward your websites). Also has another button that allow you to review your opened windows and folders. In general I think it is a great option.

This was just right for my hand. I have a medium sized women's hand. I was having ergo issues at work with the mice offered (county government of course) so I purchased my own. I was having pain in my right thumb joint inside because I needed a mouse that lets me rest the base part of my thumb on the mouse without gripping too tight or not having a space on the left side of the mouse. After I purchased this and used it, I don't have any pain there anymore. I got my supervisor to order me one at work and now I use this one I bought at home with my laptop (instead of the mini one)..way better. Thank you!

I have been a fan and user of the logitech products since the MS DOS days. I needed a Bluetooth mouse for three devices (iPad Pro, Chromebook and Win10 laptop). And I needed Bluetooth interface. My use is Home-Office. The Triathlon fit the requirements AND it performed better than I hoped. The single button below the 123 easily switches control between these devices. Yes, I had all 3 working at the same time. I like the lower-left side button to display all open windows. The scroll wheel has no dead play, so scrolling is precise.

I’ve had a few mouses here & there but this one so far has been the best one yet for me personally. For a while I was using cheap mouses and it actually feels nice to have a good mouse! The battery life last a long time! To the point where I even forget I’m using batteries [Pros] 1. Comfortable handling 2. Three different connection modes like (Proprietary USB, Bluetooth) 3. Button to change the scroll wheel speed from a fast wheel to a slow ridged speed 4. Battery life is long 5. Good connection 6. Auto Shut Off [Cons] 1. No rechargeable battery (you have to buy your own battery’s) 2. Sometimes! My computer doesn’t recognize it “but I’m not sure if that is the computer or mouse” 3. I accidentally click the (Thumb button) and it gets in the way of when I’m doing something [Verdict] Still my go to mouse to this day, and it’s already been more than a year of use! :) I really like the mouse! If it comes to the time to get another one I would probably buy this one again or something similar
