This is the latest addition in my mouse family and it is being used on my better half's computer, on which I lately spend most of my on line time so a purchase of the mouse was a must - I hate "mouse pads". The one I bought is almost as in the picture Dooyoo provided with exception that top part of the mouse is blue instead of black. It is an optical wireless mouse.
This mouse is really small which is as the name suggest perfect for traveling or if you as I have small hands. It is also very light. But not only the mouse is small, since it is wireless it has to have a USB receiver and this one has the smallest I have personally seen so far - it is as small as a fingernail, if you have big fingers then even smaller! You can have it in your laptop or any other computer all the time it really will not bother you and the laptop will still fit normally in the bag, alternatively you can unplug it and store the receiver into the mouse.
It has 5 buttons, your regular left and right - they are very responsive and make a subtle click sound when pushed, a scroll wheel - it rolls smoothly and almost without a sound and a something I would describe as page up and page down button located above and below the scroll wheel called "Turbo scroll" - it basically is that a fast scroll buttons, might not sound as much but it does get handy.
It also has a red connect button on the bottom in case your computer looses or can't establish connection with your mouse but I did not have to use that button as for now.
The mouse is pretty accurate so it will be good for some moderate game playing it is really responsive.
It is good on most surfaces although it does not cope well with my bed (my other mouse does!), so I have to use something (usually a book) for it to work satisfactory.
It does not use up batteries much and you also have a ON/OF button to save up even more energy. It needs two AAA batteries.
It is on sale for £17.33 on Amazon at the moment, I got if for a bit more from my local store.
Genius Traveler 900 features a 'Turbo scroll' function for instant browsing over long page documents or Internet pages. The advanced 1600 dpi power saving optical engine is great in movement control as well as excellent anti- interference function for its advanced 2.4GHz wireless solution.
