Dependable, Reliable

As advertised. Logitech, best mouse for your hard-earned cheddar! It’s not that the (years) old Logitech mouse failed in any operational way, it just got that gummy, sticky surface texture that’s impossible to remove. While shopping for a replacement I noticed an off-brand mouse/keyboard combo and thought, “hey, 2 for 1”…mistake. All was well for about three weeks, long enough that when the gremlins arrived I didn’t immediately associate the new hardware. For the purposes of this discussion, gentle reader, know that I run legacy (what I affectionately refer to as, “Lazarus”) builds. Rigs that started life running Windows Vista/7, died, and that now, resurrected, run 10 and 11, and all that that implies. So, when a mouse started stuttering, of course I thought it was a gremlin in the machine, right? I spent more days than I am comfortable sharing with you pouring over processes and background apps, and registry trims…before Accam’s Razor suggested I eliminate the mouse as a variable. Changing the battery was ineffective, but when I swapped in the ooold Logitech…Yahtzee/Bingo/Booyah…smooth and precise…butter! All I needed was a new Logitech mouse. So, if you’re here you likely are having mouse issues of your own, or you just need one that works…this is it! 😉

Nice and a great value.
Color: Swift Grey, Size: 1 Pack, Style: USB Receiver
Hey, it works well. Just plug it in and you are ready to go. Only issue, minor, no light or color coding on back to indicate on or off.

Simple and efficient
Color: Swift Grey, Size: 1 Pack, Style: USB Receiver
This is a dandy little item. Easy to use straight out of the box, No fancy bells and whistles.but why should a mouse try to replicate commands that are on the laptop?

It's a good working mouse but it's loud clicking and a little small.
Color: Swift Grey, Size: 1 Pack, Style: USB Receiver
I thought I was getting a quite clicking mouse but this is not it. I may have misunderstood the description or confused this mouse with another while researching. It's not a five star for me because it clicks loud and it's small and too easy to accidentally click one of the buttons when you don't want it clicked. The accidental clicking happened a lot and was becoming frustrating. As a working mouse, it does its job and it's reliable. Overall, I like the appearance of it and it feels nice and grips good. I think the price is reasonable for this product. I ended up getting a quite mouse to replace this one, but I am keeping it as a backup.
