The Logitech M510 Wireless Mouse is what I use as a backup mouse for my laptop at home. I actually like it a lot it has a comfortable ergonomic grip, a high performance laser and plenty of bindable keys for gamers.
The overall mouse is a glossy two tone black mouse. There are other colors available such as blue.
In the image above the two side buttons are very visible. These two buttons have a firm recoil and click nicely to let the operator know when they are pressed. They are comfortably located above the ergonomic thumb groove.
The scroll wheel on this mouse can be depressed and functions as a center mouse key. It also scrolls allowing web browsing with ease and the scroll wheel can be moved left and right which functions by default as a page forward and page backwards button. Utilizing the Logitech software all buttons can be rebound to other functions as desired.
This is a full sized wireless mouse and is comfortable for my hands (which are on the smaller side). My main mouse, a Logitech Wireless Mouse M560, has a bad habit of the side button closest the the user being accidentally clicked. The accidental clicking could be due to my short fingers but I have had to disable that button in my main mouse. This backup mouse however does not have the problem of accidental clicking.
On the underside there are four pads which allow the mouse the easily slide on most surfaces I personally use it on an ergonomic gel pad I love but the mouse works equally well on a wooden lappad and the cloth couch. The bottom of the mouse opens allowing a user to change the battery (which is rated to last for 2 years and was included with the mouse!). Inside the battery compartment is a storage slot for the dongle allowing the owner to not lose the connectivity piece when mobile.
The only reason I got a different mouse is because my one year old toddler eloped with this one and I was on an overnight trip and didn’t have time to look for this one. My newer mouse the M560 and this mouse the M510 are both solid mice to purchase and I would recommend either one. I will be reviewing the M560 soon and you could read that article for comparison if interested.
