Despite the fact that a lot of us lefty mouse users are naturally right handed - it's more efficient - there are precious few models out there offering anything like the range of functionality available in right handed designs. This M650 is an exception and the controls have a good range of built in and customizable features. Mine are quite basic but I do like to add copy, cut and paste functions to the additional, left, center and right side buttons. When I set it up it showed a battery status of 80%. Within days this had risen to 85% so now I need to find a house sized one for all my electric needs.

I have bought two mice in this series first the M330 and most recently the M650 in April 2022. First, I will say the mouse feels great, is comfortable and is extremely quiet. However, my experience with both mice is that left click button has trouble registering clicks after a few months of use. Once I started noticing the issue, it seemed to get progressively worse. It starts out with missing a click out of every hundred clicks, now it seems like it will miss one out of every 5-10. While the mouse does get used regularly, I would not say it is used heavily and it is well taken care of. My experience is that these have a very short life span, which is a shame because I would surely give this mouse a 5-star rating if it didn't become incredibly frustrating to use and require replacing within a year.

First, I'm a lefty and have had to deal "ambidextrous" mice for years. This mouse (M650L) finally allows me to take advantage of all functions without having to worry about inadvertent actions. I have relatively large hands and this mouse fits my hand nicely. I also like that it can be connected either by Bluetooth or USB, as my laptop's Bluetooth isn't the most reliable. Overall, I couldn't be more satisfied with this mouse and highly recommend it.

It works great, but there is something different about the ergonomic design. I continuously accidentally press the right click button. That didn't happen with my previous M510 model. I wanted a left-handed one but there wasn't a M510 for left-handers.

[This review was collected as part of a promotion.] I bought an M650 mouse which worked perfectly with my computer. But it lacked the ability to work with (run away from) my cat, Shadow. He destroyed it. I have replaced the M650 mouse with a new one. The new one is kept safely in my hand or a drawer and he plays with the destroyed one.

[This review was collected as part of a promotion.] It is a great product to work woth.Silent as mentioned in the description and has various functionalities where we can customize the buttons through the logitech application which in terms of innovation is great. Color and texture of the mice is great and has a modern design touch to the mice.

The cat who often sleeps on a pillow on my laps is offended by the sound of mouse clicks. Over the years, I have tried three models of silent-clicky mouses, with the M650 being my favorite. I like it because it has soft-ish rubber sides, a rubber-coated scroll wheel that spins silently, and most of all, near-silent finger-button clicks. At first, the smaller size of the mouse seemed weird, but now that I am used to it, the bigger mice seem too big, and I have medium-sized hands for a man. I am glad it does not have an RGB light show, which I find distracting. The thumb buttons on the left-side are useful to have but placed too far back for my thumb to reach them comfortably. If Logitech were to put the silent features into some of their more ergonomic (and expensive) mice, then I would definitely spend my money to upgrade, especially if it was one of their mice with the side-scrolling wheel that is useful for editing video and looking at spreadsheets. As for now, this mouse checks the most important boxes, and I am glad to have this option for a silent mouse.

[This review was collected as part of a promotion.] This is an awesome mouse. It's accurate and precise. The buttons are positive with no slop like earlier Logitech products. The wheel feels very high quality, as though it will last a long time. My only beef is not with the product but rather with the guidance on the size to choose. I have very small hands for an adult male and obviously fell into the "small/medium" range on the size graphics. So that's what I ordered. That size is REALLY small, much smaller than my previous Logitech mouse. I am pretty sure I would have preferred the Large size. It's taken me a week or two to get used to the size and it will be fine, but it's not as comfortable as the larger mouse was. Order accordingly.

I received it pretty well packaged and full ! Loved it :heart_eyes: But still i don’t understand why the mouse time to time stops responding or moves very slowly and I need to click few times the little circular button to kind of restart it. Fit was great , my hands are small so its very hard to find a mouse which would fit it completely, this was a right choice (L) .

Mouse feel smooth and light, I have the L size and fit comfortable in my hand, my only issue it's with the Bluetooth connection because sometimes the pointer takes few seconds to came back and delay after you are not using.... The USB connection it's the opposite, super fast with no delay or lags
