Great Value, Compact, & Reliable Mous
Color: Blue, Style: 1-Pack
The Amazon Basics 2.4Ghz mouse works well right out of the box. I really appreciate its compact size, as it doesn’t take up much space on a mouse pad or flat surface—great if you’re working in a limited area. Its ergonomic design also feels comfortable under the hand. Overall, I think it offers good value for the money, and it’s very easy to set up and use. So far, the battery life has been solid—I’ve used it for three months and it’s still going strong. I put in Amazon Basics battery in this mouse, and surprisingly it lasting a long time.

A Simple, Effective, and Inexpensive Device
Color: Silver, Style: 1-Pack
I have tried many variations of the standard computer mouse over the years. You probably have too. From weird angles, extra buttons in the scroll, funny side buttons that only make you go backwards on your web browser...Sometimes, you just want a point, click, scroll...and that's it.
Pros:
- This mouse delivers on simplicity. It doesn't have fancy advanced features. This basically functions as a point and click. It has a left and right hand button to do those old fashioned right and left button tasks. It has a basic scroll button. It's low tech features, but quality built for those features that it has.
- It seems to work on most surfaces without a mouse pad.
- Cost is ridiculously low. It's almost so low that you question its quality. In this case - it's Amazon. Amazon has really delivered on their Amazon Basics division. This falls neatly into that category of awesome but inexpensive Amazon Basics stuff.
- Connected within a second to my computer (Mac). I don't see any connectivity issues. I didn't have to download drivers at all.
Cons
- I haven't used it long term yet so if there is a break down, or the battery life turns out to be poor, I will update. For now, it's behaving beautifully.
Overall, if you miss a nice, simple, uncomplicated mouse - start here. Worst case scenario, you can return it. After all, Amazon has been standing behind their stuff for a while now so I'm not afraid to start with theirs and see how well they did. This is another one that didn't disappoint and it cost 50% less than its nearest competitor (at the time I bought it at least).

Mostly a Really Good Mouse
Color: Silver, Style: 1-Pack
This mouse connected perfectly, feels good, and even works seamlessly with my cordless keyboard, which of course uses a different dongle. I have only one small issue, but it's one I thought worth mentioning. While the buttons work normally when moving the cursor around the screen, when it comes to actually making a selection with the primary button (right- or left-handed, doesn't matter), one must press the button VERY deliberately and somewhat slower for the "click" to be recognized. A typical "quick click" at the speed one would normally use, say, when typing or normal "mousing" often will not register with the computer. The result is that I have to slow down and click again. In several decades of using a computer mouse I've never experienced this phenomenon. I've grown used to it, however, and adjusted to the necessity to give the selection button a slower and harder "press" when making selections, and that's all it takes. And oddly, it only requires this extra deliberate action when pressing a selection button. Not the biggest issue one could have, but I thought it worth mentioning. Other than that, no problems, and really, the price is very good, so as they say, you pays your money and you makes your choice. ;-)
