The length is great for comfort. Ergonomic curves allow the mouse to fit comfortably between thumb and ring finger. The length takes pressure from the wrist by allowing your fingers to rest in a flat and straighter position. Other products are too curved, with a big arch that cups the fingers. The M510 feels like you hand is just resting on a table top. Very comfortable. The buttons are quiter than generic, but yiu still hear a light click. The middle mouse wheel is a bit wobbly because it clicks left, right, and down (so the mousewheel has a 3 way switch, and also scrolls). The side buttons are large enough to feel certain about which you are on, thanks to a curve in between the side buttons. The USB dongle is easy to take out of the battery conpartment, plugs into the computer, device is detected, and you can use the M510 straight away. You just need to remove the divider between the battery contacts (seen in the pictures). The batteries come with the mouse, but i would recommend buying some rechargeable. Nothing like gaming and suddenly the mouse quits working due to a battery running empty! Overall, a good product. I would prefer the middle mouse button / wheel was sturdier. It feels a bit flimsy and I suspect it will be the first part to fail. However, having the 3-way wheel buttons is going to add more options for the operator. There is no DPi button to quickly change cursor speeds, so your mouse settings will have to be done in the control panel of the computer. The optic is infrared, so there is no visible red laser light from the bottom. Using 2 batteries makes the M510 a bit heavier than some other options, Once I started gaming, I forgot that i was even using a new and different mouse. It feels natural, it works good. Worth every penny!

Works like a champ. Takes a single AAA battery (included). Good product, great price.

Easy to install. Works well for small price. I have an apple Magic Mouse and I prefer this mouse over that one. Smooth working as I am working on spreadsheets and answering emails.. I am not a small girl so this mouse fits my long fingers well.

This is a great inexpensive mouse, as long as you're not using it across the room or with anything directly impeding the very weak signal/receiver.

So far I've purchased three of these mice for office use and design work. The mouse wheel being able to side scroll is the biggest reason why I love this mouse so much. You may be wondering why I purchased three and thinking I did so because the others broke or wore out, and that's not the case. The original one I purchased is still being used in my office at work. The second one I purchased is for use at home when working remotely. And the third was purchased to store in my laptop backpack so that I always have one with me when traveling. I just really like this mouse and it works very well for me. I've never had connection issues, nor have I noticed any lag when scrolling. It's a solid, sturdy mouse, and does its job well. In terms of battery life, I've had to change the battery once, and that was for the very first one I purchased. I've still not had to change the battery on the other two yet. I'm sure there are other newer versions of this mouse that do more and are shinier, but this one hasn't let me down yet, and the price versus quality is unbeatable in my opinion.

It's been a while since I used a mouse instead of a touchpad. The buttons and wheel are a very comfortable change. The mouse is a little small for my very large hands, but that seems the norm. Well designed, the buttons are right where they should be with no confusion on what I'm looking for. Stays connected, no idea on battery life yet.

Replaced an old mouse for use with my laptop. Accurate and ergonomic. Best mouse I've owned in 30 years.

Works and clicks like it does when I first bought it nearly 3 years ago. It’s even been running on the same first battery. As a utilitarian tool, it does the job and it simply works.

Came very quickly. Easy to pair and works right away. Great build quality. Would buy again.

Gracias, gran producto

An excellent product and well worth the money. It is the best most that I have ever used and I would certainly buy it again.

Es sumamente rapido para conectarse y preciso en su operación, muy recomendable

I've been using this mouse for a few years now. It's the perfect size and weight. The buttons feel really good and tactile. It's the only mouse I will ever buy so long as they keep making it. Battery life is insanely good. Very durable, I've dropped mine probably a hundred times (not an exaggeration), just keeps going.
