This mouse (M650L) fits my hand perfectly. I love the Bluetooth connection (no dongle at all hanging off my laptop computer - but it comes with a dongle if you really want wireless USB connection). This should be the standard bearer for all mice. Note there is a smaller size and a larger size of the same model. I tried the smaller size (M650) first and it made my medium-sized hand cramp. Then I ordered this larger size of the same model (M650L, the “L” stands for Large). People with very small hands might like the smaller size of the same model. I later got another one of the large size for my college age son (with medium size hands) for a gift. He liked it so much he actually made a special phone call just to me to thank me for it(!). He also went on and on about how comfortable the M650L mouse felt in his hand. I gave the smaller M650 to my wife (very small hands) and she likes that size. Works great. Batteries have lasted over a year with every day use. I love it! Note there are about six or so different colors from which to choose. This is a right-handed mouse. There is a left-handed version available in the large size. I don’t know if there is a left handed version of the small size or not… This is the only mouse I ever want to use in the future!

I've been looking for a reasonably priced mouse that is both quiet and efficient. This absolutely fits the bill. First it's compact and light (a bit too compact for me, unfortunately), and the mouse buttons are absolutely silent. I use this in an office setting, so I like my keyboard and mouse clicks quiet, especially when I'm on calls. Paired with an MX keyboard, this is an ideal accessory. I could see students appreciating this in a dorm room or in a library when studying.The mouse comes with a standard AA battery (not rechargeable), with a USB-A universal dongle inside the battery compartment, which is convenient. My windows system immediately recognized the mouse on both Bluetooth and 2.4 Ghz, so pairing was super easy.There are two side buttons, which are initially used for going forward/backward on web pages, but you can reprogram the keys using the logitech software. I don't love that you have to download the software and keep it running on your machine, I'd rather have a web-based interface. One thing to note, the side buttons are NOT silent like the main mouse buttons, but they aren't too loud.One feature I do appreciate is the fast/line-by-line scrolling wheel so you can scroll quickly or slowly. It's not as smooth or as fast as the MX Master 3 mouse, but it's better than any other mouse for this feature.For the price it's a great deal, the only caveat here is that it's a bit on the small side for me, and I have regularly sized hands for an adult male. Still usable, and some people may even prefer this, but for me I'm going to go with the larger size.

I am very picky with mice and wanted something that would replace the most perfect mouse I've ever used: the Microsoft Intellimouse Comfort 3000. I would still be using that mouse if Microsoft updated the drivers for it, but strangely, no one uses this mouse anymore.My requirements were a lightweight mouse that had a thumb button and a wheel with acceleration. Once you've used that, you can never go back. Most people gravitate to the Logitech MX Master, but I disliked the size and weight of that mouse. The wheel also didn't glide through pages as nicely as the Intellimouse. That's where the M650 comes in.The Logitech M650 is super lightweight and can be made even lighter with an AA to AAA adapter. It now rivals the weight of a corded mouse. The scroll wheel has the ability to scroll slowly or quickly with a flick of a finger, virtually like the MX Master, but without the heft. On a single AAA NiMH battery, the mouse lasts about 6 months before needing a recharge. It can connect through bluetooth or the dongle (sadly only one or the other). The clicks are silent yet tactile. It's a thing of beauty.The problem comes with the unstable firmware. When it works, it works great, but it will randomly become unresponsive for a few seconds or the cursor will become jerky. The freezing will correct itself, but the jerky behavior usually needs a power cycle of the mouse.Hopefully Logitech figures out what's causing the instability and fixes it. This mouse is near perfect and I'm sure as more people start using the smart wheel, the more people will love it.
