Bad auto driver install. Great mouse. Few of the left hand mfgs.
Style: Left-Handed, Pattern Name: Mouse, Color: Graphite
Really crappy auto driver install. Locked up my USB ports for my usb keyboard, usb mouse, all usb ports in fact. Had to reboot multiple times with an old style 5pin keyboard since the software screwed up my usb ports. All of them. Lucky I have a motherboard with an old style keyboard port. A reboot of W11 in safe mode, ripped out auto-installed software, registry keys and rebooted to regain control of my USB ports. I do not know what went wrong. Alls I know is Logitech loaded something, it locked up my USB ports and I had to rip everything Logitech out to get control again. I downloaded the software, installed it and it worked fine. I've had no problems since.
I'm an old lefty and as such am ambidextrous in most areas, since there just was not left handed oriented items readily available. You had to have left handed stuff made so you learned to do things right handed. I've developed carpal tunnel in both elbows and had purchased a couple of vertical mice, one left and one right. I took the left into work and was looking for a replacement. My other two were around $30 ea. I liked the right handed vertical mouse (Anker). They do not make a left handed version. The left handed mouse is ok, not as good as the Anker. I decided to go above my spend tolerance and get the Logi after reading many reviews. It has not disappointed me. The auto-install sucked. Never letting that happen again.
It is a nice smooth mouse. Fine movements that are easily adjustable. The hand position is excellent. I can use this all day without switching to the right because of elbow pain. If you have the pain, you know what I am talking about when it flares. It takes some getting used to the subtlety of the clicks when coming from lower cost mice. Soft and gently like a newborn's ....
One of my big criteria for a vertical mouse is a landing area for the outer two fingers (pinky and next to pinky for finger orientation challenged). When you go to a vertical mouse, it takes some adjustment to moving the mouse since you can't really press down with your palm and inside two fingers (the ones next to the outside two fingers). It is helpful to be able to use the two outer fingers and thumb to aid in moving the mouse. You have to experience a vertical mouse to understand. The right handed only Anker goes from an inch to a half inch in the length of my pinky below the buttons on the side. This is a really nice landing area for the outside fingers to assist moving the mouse around. You can squeeze a little and the mouse glides. The Logi mouse is a wee shorter than the Anker and the area below the buttons in a mostly straight 3/4". Both mice curve quickly down to the inside below this area. I was used to a vertical mouse by the time I purchased the Logi and I have no issues with the pinky dragging the table and the finger next to pinky resting on the landing. I move the mouse with no problems. It is the subtlety of how one interacts with these style of mice. The big plus, takes a long time before mouse use causes pain flareups. And this isn't just a pain and done. Depending on how one ignores the pain, often determines how many days life sucks. The Logi mouse minimizes the flare ups. I'm thinking of taking the Anker in and getting a right handed Logi for home. I like the Anker, I'm frugal and highly recommend it for getting your feet wet. I love the Logi (auto-install sucks) and will probably ignore my frugal tendencies and get a right handed one since I don't switch hands as frequently with the Logi in the mix. Don't have to suffer auto-install either.

Shape can be a game changer to reduce arm/wrist pain
Style: Right-Handed, Pattern Name: Mouse, Color: Graphite
Very easy to setup with PC, whether by bluetooth, usb, wifi. It does take some time to get used to the new design. The scrolling is very good and all functions are extremely responsive. So far, it is not causing any strain to my arm and wrist which is why I am trying this design as my older, normal shaped mouse, was causing me arm pain. They should include a quick easy to understand information sheet about the buttons. Need to download in order to customize 2 other buttons. All in all, so far I like it and definitely suggest it for people having arm or wrist pain from the angle and position of a regular shaped mouse.

Wonderful!!
Style: Right-Handed, Pattern Name: Mouse, Color: Graphite
Update -
After using this mouse for over a year I started experiencing something profoundly annoying. When dragging something from one place to another (often from monitor to monitor) I would accidentally hit one of the buttons by the thumb and it would close whatever I was working on. Especially during work where I do this often. I found there is an option to turn these buttons off in the software!!! Wonderful!!!
That was the absolute only thing I was having an issue with. Longevity has been perfect and I'll confess, I'm not particularly regular about cleaning it. I would buy this mouse again in a heartbeat.
I bought this at the same time (Feb '25) as the Logitech Ergo K860 Wireless Ergonomic Keyboard - Split Keyboard, for which I have also written a review.
I cannot say enough good things about both of these products. My neck, shoulders and back feel so much better than with my previous setup.
At the time of purchase, there were a number of reviews saying these failed fairly quickly. This has not been my experience and I am not very conscientious about cleaning it.
After almost a year of heavy use (8-10 hrs a day), the batteries are at 30% which I don't think I can complain about.
These products are not cheap, but for me they have been worth every penny and I cannot see myself going back. I'd buy them again in a heartbeat.

Easy setup, beautiful red!
Color: Red, Color: Red
I needed a mouse for an assignment when I asked my son for his. I loved it so much that I needed to buy myself one. I bought the red to match my computer (and to know that the navy blue is my son's) and it's a very sleek, not tooo vibrant color. It does come with both an USB & USBC controller (see pictures) and mine connected FAST to my computer. It does NOT come with a battery (most mice won't) so please grab a DOUBLE AA battery before it comes in so you will be ready. I have no issues with the mouse and loved the price point on this one. It's light weight and easy to setup. Then again it was a plug in/play setup, so if you're not tech savvy, you won't have issues with this one. Just choose a color and get it!

Cut the Cord and Never Looked Back!
Color: Grey
I'd been using a wired mouse forever and kept telling myself the cord wasn't that annoying. Spoiler: it was. The moment I switched to the WisFox 2.4G Wireless Mouse, I realized what I'd been putting up with all along — and there's no going back now.
Setup was dead simple. Plug the little USB receiver into the laptop, and it just works. No drivers to hunt down, no pairing headaches, no nonsense. The 2.4G connection is solid and responsive — I haven't noticed any lag or signal dropout, even when the receiver is tucked into a port on the back of the laptop. The cursor tracks smoothly across my desk surface without any skipping or stuttering.
The ergonomic shape is a genuine plus. It fits naturally in the hand during long sessions and doesn't leave my wrist feeling fatigued the way some flatter mice do. The buttons have a satisfying, tactile click without being loud enough to bother anyone nearby.
My one gripe — and it's pretty minor — is that it runs on batteries, which means you'll eventually need to swap them out. It's not a dealbreaker by any stretch, and the battery life has been reasonable so far, but if you're used to a wired mouse that just runs forever, it's a small adjustment to keep a spare AA or two around.
Pros:
Instant plug-and-play setup with the USB receiver
Reliable, lag-free 2.4G connection
Comfortable ergonomic shape for extended use
Great freedom of movement without cord clutter
Cons:
Runs on batteries — plan to keep a spare on hand
If you're still tethered to a wired mouse and on the fence about making the jump, this is a solid, no-fuss way to do it. Hope this helps!
