Customer Ratings & Reviews

Was having wrist issues with a regular mouse and trackpads so did some research and found this device. It is great at providing relief from the typical stress points in the wrist that are affected by repetitive stress injuries. Highly recommended.

very comfortable to use accurate speed and pointing

I don't have huge hands. I have small hands. Reviews seemed to say that people with small hands found this comfortable and usable. So I decided to try it. At first, I thought I liked it. But I started to notice that it wasn't always responding to my left clicks. I finally realized that was because my hand was slipping back and my finger wasn't clicking on the optimal area. Then I noticed the side buttons...which I hadn't noticed before because I couldn't reach them. Also, my arm was getting tired because I had to hold it raised to keep my hand up on the mouse. To use this properly, I'd need some kind of wrist rest to drag around with the mouse. So I've given up and am trying a tiny mouse now. I feel like Goldilocks. Anyway, if I'd kept the packaging, I'd return this one. I would recommend this mouse to a friend--but only a friend with large hands.

Exceeded my expectations. Once you get used to the feel it's very smooth

Like the tilt, hate the buttons and the scroll. They're making my RSI go up through the roof. Super hard to click or scroll.

Very smooth and flawless operation. Very comfortable.

You'd think that this vertical structure would make for a better hand position but it doesn't. About the same as their regular ergonomic mouse. The two worst thing are the button positions and the fact that each time you click you move the mouse. Not worth it.

Very mixed feeling about the design. For desktop use it is fine after a period of adjustment. It gets dirty very quickly due to sweaty hand. It's very hard to control fine movement with a full hand. That's the major design shortcoming of the otherwise innovative approach to wrist ergonomics.

It was hard to hold and move especially with carpal tunnel syndrome. I originally purchased it due to CTS because I thought it would be more ergonomic for my CTS but found it otherwise harder to control and made my CTS worse.

Some love these, but I'm not so sure... yet. I wound up getting a much less expensive corded one from another retailer to have in my mouse box when I feel frisky and want to try this design out more. Maybe in the future these types will grow on me. YMMV

Reliable Rapid control of cursor with optional volume control

This mouse is good for arthritic hands. Easy to use.

This was not what I expected when I purchased. I have Essential Tremors & it was hard to maneuver so I returned it. Probably would have been a great add on to my office

I did like this mouse for a while but after extended use, over several months it started to cause bad wrist pain and a bump developed on my wrist. stopped using the mouse and the bump went down and pain stopped. really wanted to like it but had to stop using.

Good alternative. Not up to par with MX series with similar price range

Love this mouse. I pretty much use the computer all day long. Once I switch to using this mouse my wrist is less fatigue.

So far so good, it took me like 5 minutes to get used to it. My wrist gives me no pain when I use it, very comfortable in the hand, would recommend if you have any wrist pain or want to prevent any wrist stress.

Defective "Left Button Switch" stopped functioning after 14 months (well-documented issue) right after warrantee expiration. Average use, 3-4 days per week. BBY, please urge Logi to address this defect. See YouTubes on soldering the faulty switch. Is that an appropriate remedy for consumers <2 years after purchasing a high-end sku?

Great mouse and great comfort not like standard mouse.

* Cannot use at all with an updated Win10 machine because will not appear over bluetooth in Settings > Add Bluetooth Device. * On macos, the FLOW software does not work; the cursor will move to the second desktop and get stuck there without ability to go back to the first screen. * First mouse in forty years that makes my palm sweat. * Overpriced.
