Logitech MX 400 Performance Laser Mouse - mouse > Reviews (5)

The mouse itself is quite big, its really made for desktops and although it'll work fine on laptops the mouse is quite large and the cord is lengthy so if you intend to use this mouse primarily on your laptop - it may fit the bill but the cord length may be a bit too big for some.

This mouse uses laser tracking technology and I can see the big benefits of this over optical tracking. I can even use this mouse on my hand as precisely as I can on my desktop...it works on a few more surfaces in my house than my optical mouse. The tracking and cursor movement of this mouse is generally the same as other mouses. I've tried many mouses and some are more or erratically more sensitive than other mouses, and by that I mean the speed of the mouse in cursor movement compared to other mouses on the same speed setting. This mouse is fine, however. A few speed adjustments via the Logitech Control Center may help though, which is included when you purchase the mouse.

The scroll wheel is OK, although its difficult to middle click due to the vertical scrolling feature the scroll wheel has. Just push the scroll wheel to the left and it scrolls vertically leftwards - vice versa for pushing the scroll wheel towards the right. It's difficult to middle click without accidentally pushing it towards the left or right for it to register as scrolling. I don't normally middle click with this mouse due to this problem, and just CTRL + click to open links in a new tab.

The mouse also has side buttons to the left for going back and forwards through web pages in the web browser...its been around in mouses for years now but its a nice added touch.

The only problem with this mouse for some is that the mouse is made in a way that means only right-hand users will be able to hold the mouse properly (and subsequently use it, either)...so this mouse is definitely for right-hand users only otherwise you'll have problems holding it.

Overall its a good mouse but its not exactly the best I've owned; but I don't mind using it - its a nice mouse to use. I think it also comes with a 5 year limited warranty. I paid around £15 on Amazon UK for it, I think, which for a brand like Logitech is a good price; but I wouldn't pay any more for it.
