Nice step-up Bluetooth mouse
I’ve been using baseline Logitechs for decades. However, this step-up model is able to pair with more than one PC so it can be quickly switched between them depending on which PC I’m using. A small push-button on the bottom selects the connection. The mouse also contains in the battery chamber a small USB dongle which allows the mouse to be used on a machine without Bluetooth.The feel of the mouse in use is excellent. The size is perfect, not too small for my hands nor a handful. The wheel is extremely responsive. As usual, I decline to install the Logitech extra driver to avoid any proprietary complications. It’s only asked me once, so far.

Fairly Large and Would be Totally Satisfactory for Most.
I have large hands and was sad when my old, very large Microsoft mouse began to fail. I looked at several possible replacements, and was tempted to purchase a Lenovo ergonomic model, large (almost mountainous) and angled at 45 degrees, which really fit my hand well, but eventually felt too extreme in angle and bulk and so I purchased this more conventional Logitech model that is stated to be designed for larger hands. However, the pinched-in sides and lower palm swell made it feel smaller and, in retrospect, I began to appreciate the comfort of some angulation, which this Logitech lacks. I finally settled on the German-designed Cherry, which has a full palm swell and is canted just enough to make it more comfortable (to me) than conventional mice, like this Logitech. The Logitech functioned very well and, I’m sure, would be perfect for most people with larger hands. It’s only my experience with the Lenovo (its “dongle” remains plugged in as “backup”!) that made me me perhaps too critical of conventional mouse configurations, like this one.

Great
Great for people with big hands! I love it.

Unusable. Mouse buttons are way too sensitive. Replacement just as bad.
The mouse buttons, especially the right one, are so sensitive, they often click just from resting my fingers on them the way I’ve done for 20 years. The mouse is completely unusable since the context menu keeps popping up all the time. I did an exchange, hoping I just got a defective one, but the replacement was just as bad. I cannot imagine anyone actually using this mouse unless they constantly strain their finger muscles to keep them hovering above the mouse buttons. Also, this mouse lacks the side-to-side click of the middle scroll wheel.

Great mouse, fully customizable in Logi Options+ app for Mac and Windows. Comfortable ergos and easy three device switching for connecting the same mouse to my work laptop, personal laptop, and iPad. Also has the old school dongle for using with devices that don’t have native Bluetooth.

Vraiment parfaite, fonctionnalités intéressantes.Connexion très rapide, silencieuse, précise.Je recommande.

L’emballage était ouvert, la batterie installée et la souris en position “on” (marche), je fus déçu sur le coup mais comme elle fonctionne bien j’ai décidé de la conserver malgré que j’ai du recevoir une souris d’un client qui avait retourné ce produit. Je ne pouvais pas me permettre d’être sans souris plus longtemps, ça aussi a aidé à ce que je la conserve malgré qu’elle soit usagée!
