Reliable and comfortable for daily work - Great value!
I’ve been using this Acer wireless mouse for a week now, and it’s a solid performer for the price. As someone with slightly larger hands, I often find travel mice too small, but this one is a comfortable medium-to-large size that fits naturally in my palm. Pros: • Plug and Play: The USB-A receiver worked instantly with my laptop—no setup required. • Ergonomics: The contoured shape is great for long office hours and reduces wrist fatigue. • DPI Switching: Having 3 adjustable DPI levels is very handy; I can easily switch speeds depending on whether I’m navigating spreadsheets or browsing the web. • Extra Buttons: The 6-button layout (including the side "forward" and "back" buttons) makes web navigation much faster.

"My Emergency Mouse Turned Into My New Favorite!"
My old mouse finally gave up the ghost, and I needed a replacement fast. I spotted this Acer wireless mouse, and since it was super affordable and had Prime shipping for next-day delivery, I figured why not? And honestly, I'm really happy with it! It works great right out of the box. I just plugged in the USB-A receiver, and it was good to go – no fussing with drivers or anything. The 2.4GHz connection feels really stable, and I haven't experienced any lag or dropped signals, which is a huge plus for productivity. I also appreciate that it has 3 adjustable DPI settings (up to 1600 DPI), so I can easily switch between precise work and faster browsing. The 6 buttons are also a nice touch, giving me a bit more functionality than my old basic mouse. The product description says it's compatible with medium to large-sized hands, and I'd say that's accurate. It feels comfortable in my hand, not too small or too bulky. For the price, the quality feels pretty solid too. It doesn't feel flimsy, which is sometimes a concern with budget-friendly peripherals. The only "con" I can think of, and it's a minor one, is that it uses a USB-A receiver. While that's fine for most of my devices, if you have a newer laptop with only USB-C ports, you'd need an adapter. But for the price and the quick delivery, it's a small trade-off. Overall, if you're looking for an inexpensive, reliable, and comfortable wireless mouse that gets the job done, this Acer one is a fantastic option. It's been a lifesaver for me! Hope this helps!

Reliable, Smooth, and Long-Lasting Wireless Mouse — Bought Two!
I’ve been so happy with this wireless mouse that I ended up buying a second one—one for work and one for home. Not having a cord attached to my computer makes such a difference in keeping my workspace clean and easy to move around. The mouse glides really smoothly, whether I’m using it on a mousepad or directly on a hard surface. It’s responsive, comfortable to use for long periods, and doesn’t lag or skip. I use it daily for 8–10 hours, and it’s held up great with no issues at all. One of the biggest surprises has been the battery life. I’ve been using it for months, and it just keeps going without needing frequent battery changes, which is a huge plus. Overall, this is a reliable, comfortable, and affordable mouse that performs exactly how you want it to. I’d definitely recommend it, especially if you’re looking to ditch the cord and simplify your setup.

Nice enough but with issues
My old MS mouse finally died, and so did it's backup. They were a very good product but too narrow for my hand. I wanted something wider this time but for some reason, wider also means lots of buttons I don't need and very expensive. This mouse is a better width and generally works really wheel but has a couple of annoying issues. The big one is the automatic shut off. The timer for shut off is WAY too short. Maybe it's appropriate for a feature on a smartphone but not for a computer mouse. It shuts off while I'm typing or reading something which is very annoying. A timeout in minutes does not fit the need or its use. A time out of an hour, or more, would work fine here an make the mouse more pleasant to use. The second issues is the "grips" on the side of the mouse don't grip. They are smooth, hard plastic. Combined with the angle of the size, it's difficult to pick up to readjust its physical position without affecting its screen position. It's something you do automatically with other mouses but it takes attention with this product.

Great, budget-friendly mouse
Really great mouse for the price! I bought this for our family computer that was using a wired mouse. I wanted something cheap but good quality. This mouse is really nice! The ergonomics of the mouse are pretty good. Scrolling is smooth. The clicks are quiet. The weight is heavier than I would have liked (probably due to the battery), but it's not deal breaker. It goes to sleep mode after a while. However, clicking a button wakes up the mouse instantly. It has forward and backward buttons on the side, which are very nice and convenient to have. Overall, for the price, this is an amazing wireless mouse and I would definitely recommend it for those who want a budget-friendly mouse for general/productivity use. If you are going to be gaming, I would recommend looking for a different mouse instead (one that is lighter and more responsive).

Better than expected by far!
Great mouse for the money! While it feels very light which is often associated with an item being cheap trash, this little guy works great, and offers the shape and feel of more expensive mice. I use my work mouse 8-14 hours a day drafting electrical engineering files, and this shape is much healthier on my grip. I’ll include a side-by-side of my well-worn drafting mouse for comparison. Once you put the (2) AAA batteries in, the added weight makes the mouse feel substantially sturdier, and more pleasant to work with. I don’t yet know how long the battery will last with regular use, but over all, you get much more than you paid for. Nowadays, that is rare!

Best product with great price
The Acer Wireless Mouse is a thoughtfully designed accessory that brings both comfort and precision to your everyday workflow. From the very first use, it feels natural in the hand—especially for those with medium to large hands—offering a smooth, relaxed grip that makes long hours at the computer feel noticeably easier. Whether you're working a full shift, studying late at night, or simply browsing, it delivers a level of comfort that quietly supports you throughout the day. One of the most impressive aspects is its reliable 2.4GHz wireless connection. In real-world use, this means no lag, no drop-offs—just consistent, dependable performance. For example, during a busy workday switching between multiple tabs, responding to emails, and managing documents, the connection remains steady and responsive. The USB-A receiver makes setup incredibly simple—just plug it in, and it’s ready to go within seconds, which is especially convenient if you’re someone who values efficiency and a clean, clutter-free desk. The adjustable DPI settings (up to 1600 DPI) add another layer of versatility. On a typical day, you might use a lower DPI for precise tasks like editing spreadsheets or selecting small details, then quickly switch to a higher DPI when navigating across multiple screens or working faster-paced tasks. It’s a small feature that makes a big difference in how smoothly your workflow adapts to your needs. The six-button design is also a standout feature that enhances productivity in subtle but meaningful ways. For instance, having extra buttons readily accessible can make navigating between pages, switching applications, or performing shortcuts feel effortless. Over time, this kind of convenience really adds up—especially if you’re someone who spends hours on a computer each day. Another thing that becomes clear with use is how satisfying each click feels—crisp, responsive, and consistent. Whether you’re finalizing an important document, managing online tasks, or even casually scrolling through content, there’s a reassuring sense of quality in every interaction. In everyday life, this mouse fits seamlessly into different routines. It works just as well in a professional office setting as it does at home—whether you're running a business, attending virtual meetings, or helping organize personal tasks. It’s the kind of tool you don’t have to think about—it simply performs reliably and comfortably every time you use it. Overall, the Acer Wireless Mouse delivers a balanced combination of comfort, functionality, and dependable performance. It feels like a product designed with real users in mind—practical, refined, and easy to integrate into daily life—making it a smart and genuinely satisfying addition to any workspace

Comfortable for work & reliable
Sleek mouse that is comfortable to complete my workday tasks. I like the fact that the mouse has a sleep mode when it is not in use. It operates quietly as when you click something you can barely hear it. Definitely worth the purchase.

Great Ergonomic Wireless Mouse
Loving this ergonomic Acer wireless mouse. It sits really nicely in the hand, not too big or small, and feels comfortable straight away without needing any adjustment period. It works smoothly and does exactly what you need it to do without any fuss. I’m actually still a bit partial to the older style battery-powered wireless mice rather than the more in-vogue Bluetooth ones. I just find them simpler, more reliable and less fiddly overall. This one definitely fits that preference. It features 6 buttons, 1600 DPI adjustable optical tracking and a 2.4Ghz USB receiver. It connects easily to laptops, PCs, desktops and Windows devices, and I’ve even used it with my tablet and it works a treat. The forward and back buttons on the left side are a standout for me, especially when flicking through pages or jumping back quickly. It offers an 8 metre range and 3 DPI settings (1600, 1200 and 800) so you can adjust it depending on what you’re doing. It runs on 2 x AAA batteries which aren’t included, which would have been nice, and it has a visible low battery indicator via a red light which is handy. It’s also rated for around 10 million clicks, so it feels like it’s built to handle long-term everyday use without issues. Another big plus is how well it tracks on most surfaces, it’s been consistently smooth no matter where I’ve used it. The blue and black colourway also looks really sharp in person. Overall, this is a reliable, easy-to-use mouse from a trusted brand that does exactly what it promises. Simple, practical and comfortable for everyday use. Recommended 👌

Must Have Wireless Mouse
First Off Before The Full Review The Item Did Come On Time Which Was Nice And The Packaging Was Undamaged With Everything Neatly Boxed So No Complaints There. Now For The Review. This Wireless Mouse Is Indeed A Must Have. Iv Used Many Mouses Over The Time And This One Has Many Unique Features. First Off The Design Fits Comfortably On Your Hand To Fingers With No Roughness So There's No Need In Having To Reposition Just To Find A Comfortable Position To Use The Mouse, Second On The Left Of The Mouse Itself Has A Thumb Rester I'll Call It To Rest Your Thumb On That Perfectly Fits To Your Thumb's Size. The Main Feature Which I Have Never Seen Before And The One That Stands Out Is The Unique USB Holder That You Put In The Computer/Laptop So That It Works. It Is Located Inside Where The Batteries Are Put In That Has Its Own Holder, This Is Useful So You Don't Have To Worry About Loosing It When Needing To Travel Or Need To Put The USB Part In Your Pocket AS Stated Because The Mouse Has A Built In Holder For It. Color And Design Is Quite Nice Too But Design And Color That People Like Varies From Person To Person But To Me Both Are Good. Above All Else Excellent Choice For A Wireless Mouse, Especially Due To The Built In USB Holder In The Batteries. One Important Thing To Note Is That It Takes Small Batteries Trip AAA's I'd Recommend The Green Energizers Are They Are Rechargeable. (https://www.amazon.co.uk/Energizer-Recharge-Extreme-Rechargeable-Batteries-Green/dp/B01DJ2QBAI/ref=sr_1_9_sspa?crid=XMEXHP8NE003&dib=eyJ2IjoiMSJ9.H3Uq3oL4I77hQzLgMdWXbpUvEeYuReY-Ygiapu-zPlVXatR0k0fkad7Q9bzLhNgFT9KO6Oy8fdkRqK7cGUw4wVBpyqvSw9UVkRZAJFgW2ohG1oWSW49OoVfYIBQzvX2m5NoVRu5zyHA-19d7SF17GVKcD4zuGcLzf756-aTqbZ12bxxRk4j6kqm6S_w10JETXQT09260lX1q9GuOgpItOVKQBVvbdO5o2V4VtFiKwEc.jZ1vFAp_5conhL4C6i4-op-AnAyZMIZsq0lUlzBuTtY&dib_tag=se&keywords=small+green+energizer+batteries&qid=1779644575&sprefix=small+green+energizer+batteries+%2Caps%2C127&sr=8-9-spons&aref=bIusJrmLMB&sp_csd=d2lkZ2V0TmFtZT1zcF9tdGY&psc=1) Iv Put These In Brackets In Case You Want To Copy And Paste Into Amazon's Search Bar They Should Be The Correct ones. Hope This Helps.

good product
well made and has a smooth scroll . Fits really well in my hand. Plus the forward and back buttons on the left are really handy and easy to operate. I am right-handed - doubt it would fit left-handed though ...

Satisfait
Souris sans fil simple et efficace. La connexion s'est faite rapidement et je n'ai rencontré aucun problème d'utilisation. Elle est légère, agréable en main et suffisamment précise pour un usage quotidien, que ce soit pour la navigation internet ou le travail de bureau. La qualité de fabrication semble correcte pour le prix et les clics sont réactifs. Après plusieurs jours d'utilisation, je suis satisfait de mon achat.
