Great mouse at a great price

Great value for the price, the mouse is good quality and has a nice weight without having to add weights inside the mouse. The Razer program let's you fully customize the mouse.  I replaced a Logitech G500 gaming mouse with this and I'm not sorry I did, as the Logitech was more expensive but not as high quality as this mouse. I highly recommend this product.

I compared this with the reviews for the newer version, and weighted if the reviews for the Logitech Wireless Anywhere Mouse MX (910-000872) - Old Version and the price being significantly higher was enough to satisfy me. I am usually reluctant to purchase keyboards and mice online without having found a demo locally of a similar model.

I really like this mouse, probably the best I've had after many decades. I was slightly annoyed that it required the set point software (from the included disk) to program the buttons, since there's a unifying receiver that in my opinion Logitech could have saved time and money by putting the Set Point software on the unifying receiver as well to streamline the "Plug and Play" concept.

The scroll wheel works splendidly, sometimes a bit too much even after adjusting with Set Point. I play a game and accidentally bump the scroll wheel and all of a sudden it's zoomed in to the max.  Had to disable the button below the scroll wheel that is for application windows due  to it's sensitivity of being pushed/bumped.

Battery lasts longer than the other Logitech mice I've owned in the past. I change the batteries about 1-2x a month. There's a notifier that will alert 1 and 2 days before the batteries die.

I bought this mouse to replace the mouse I have at work.  I share an office with other employees and they could hear every click, click, click of my old mouse.  This mouse is definitely silent and I love it.  Loved the price, too.  I definitely recommend it.  It goes into sleep mode when you don't use it for a while but I just click on it (a silent click, of course!) and it wakes right up.  It is comfortable in my hand, too.  I would buy it again.

Great quality mouse for the price with nice responsiveness. Buttons feel great, as well as the scroll wheel. I have slightly larger hands, and this mouse size feels just right and quite comfortable. The plastic and construction does not feel as solid as my other Logitech mouse, but for less than half the price it's well worth the purchase. I've only had it for a couple weeks so far, so I will have to wait and see its durability and battery life. However, at this point I'm very satisfied with the purchase and gave it 5 stars.

This mouse is fantastic! I was skeptical about the quality at first, mainly because of the price, but this is a great buy. Fits great in my hand (male with average sized hands). I connected it to my mac and was unsure if some of the extra buttons on the mouse would work. Most work perfectly fine. The blue microsoft button serves as the 'command' key on my mac. Overall, great mouse for a great price!

The mouse feels very solid and good in the hand, with the scroll wheel feeling high enough quality despite seemingly floating between the clickers. It switches fast enough with the DPI button, and the only issues I've had with it involve accidentally hitting the back and forward buttons on the side. It's probably user oversight though, for the price it's a fantastic mouse.

This is the first Bluetooth mouse I have ever purchased.  I was a bit hesitant as I typically purchase USB mice.  I am so glad that I made this purchase.  The mouse works perfectly, easy to connect, and is very ergonomic.  I love that I do not have to use the USB port.  I also like the auto-sleep function.  I also like that it is rechargeable.

I have had this mouse for a few months now and I am extremely happy with it. The variable DPI presets are well spaced.

This is a terrific basic mouse at a great price. I'm a Mac user and all their mice of late have been troublesome. The Mighty Mouse uses a "touch sensor" for the right click but if your finger isn't in just the right place it won't register. The scroll ball is great for left-right movement but it can't be removed so it can't be cleaned properly. It's also very large and to me fits oddly in the hand. The blue tooth mouse is also troublesome as the touch surface is the entire front end so accidentally stroking it will scroll the window. This mouse corrects all that with physical, tactile buttons and a rubber wheel with soft detents. It's also sized well. I have large hands but the smaller mouse feels easier to use. With good, basic design and a great price I feel like this is a no-brainer for anyone wanting competent functionality!

I would often get annoyed when my old mouse's baterries had to be changed every month. Since I ordered this mouse (About 6 months ago)  I have never changed the 1 battery I placed when it arrived. I like the programmable buttons they are very useful, you can even assign specific commands for different applications. Aside from software,  the infinite scrolling is a great feature to have. I recommend this if you are looking for a budget and quality mouse.

Mouse is of excellent quality, responds well, and works flawlessly with my laptop.  Can't match the battery life and Amazon's price was great.  Highly recommended.

I like this mouse.  It looks great, and feels nice in my hand.  It is just a little small, but definitely not a compact mouse.  It is a little on the light side, but I got used to it after a few days of use.  I hated my last Logitech mouse after awhile because there were so many extra buttons on it that I just switch off using the software because I never use them.  This mouse is back-to-basics, with just the left, right, and clickable mouse wheel.  It is a great mouse at a great price.

Working in an office, I have been having wrist pain for the last few months. I knew it was because of how much time I spent at my computer using my mouse. So, I decided to get an ergonomic mouse to see if this would help, but after checking out other mice, I was disappointed by the cost. Then I found this mouse.

It is a perfect entry level mouse for someone looking to switch from a traditional mouse to an ergonomic one. Although the price is much lower than others, it doesn't feel cheap. It fits an average sized hand perfectly, the button placement is well spaced, and the angle is just right. The variable DPI selection is a nice touch to quickly adjust the speed.

I have noticed a few small bugs (twice in about a month), but nothing that turns me off from using it. A quick flip of the power and it's back to normal. That's the only reason I'm giving it a four. Great product for the price, and a great entry level ergonomic mouse!

I had been sitting on the fence about getting an optical mouse for quite some time. It is really hard to justify buying a $70 mouse; specially when there are so many models available.
I had been trying different models for several months and have to admit that this one not only feels right due to the ergonomic shape for right-hand use, it is well built.
Some other features I like is that it has 800 DPI (dots per inch) resolution, which makes it very acurate.
The short setup instructions are a must read, specially to have the wireless base detect the mouse. Luckily they are straight forward and easy (although small print) to read.
I have not yet tested this mouse for gaming but so far the response time is very fast (under Win2K using the USB port.) The instructions also point out that it works best on light matte surfaces, which might explain the complaints from other reviewers; it works just fine on printed fabric also.
Another feature I like is the third button close to the base. (the desk.) This makes it easier to grab the mouse without having to be overly cautions about clicking extra buttons like some models from the competition.
Highly recommended!

This mouse works great! It is comfortable to use and it is precise. I like that it goes into sleep mode when not used. The scroll wheel works great too.
