I will try to get this short and to the point. This mouse is a 2-button with scroller model and optical tech. So basicly it should be two time better than any ball mouse. Well that is true but not in the same time. The optical system is a great advantage over any ball mouse couse no cleaning in required so no more pauses to clear that ball or just crash the mouse on the pad hopeing it will work after. This model is maily very ergonomical and very light so no more hand twitches and strains. The scroll is very helpfull and allthough it is a two way (no horizontal movement what so ever) it can act as a third button as well. Ok now the bad things....the buttons wear out too easily. Especialy the left one that most Windows users use. But the worse part is the software. Allthough it installs lots of features for the mouse exaclty thhose features become a nuisance so it's better to live wthout them...now the coclusion... is it worth the cash? if you're upgrading from a baller this is your best buy. If you want to change your optical one...keep the old one unless it's broken :)
Optical mice are starting to become more and more popular with today?s computer users, whether for home or business use. Andrew Shellam examines the benefits and drawbacks of the Genius Netscroll Optical Mouse ? the PS/2 version. ============================================ Ever since I started as a computer engineer a few years ago, I?ve used hundreds of different mice ? from the standard PS/2 and USB ball mice to laptop touch pads and roller balls. But I?ve never found a mouse more comfortable to use than the Genius Netscroll PS/2 ball mouse. It is finished in a rather dull shade of grey, which doesn?t look like anything special, but it does its job. It consists of three buttons ? the standard left and right button and a roller button. The roller can be used to scroll up and down in Internet and Office documents and the software included, the Genius MouseMate 98 software, provides quick shortcuts to common features such as the Start button and your Internet browser. Genius soon followed this popular budget mouse up with the optical version ? the Genius Netscroll Optical PS/2 Mouse. Priced at around £20, it is very similar in design to the ball mouse but with distinct differences. One being the colour. It has grey coloured buttons and a darker grey roller. The body of the mouse is a sort of creamy-white colour. Secondly, it has two additional buttons to the ball version ? two ?thumb? buttons as they?re called. They even light-up when you move the mouse! If you own a Genius PS/2 standard keyboard with a wrist-rest, the optical mouse is a perfect match for your computer system. Optical mice do not use physical movements inside the mouse to produce the movement on the computer screen. Instead they house a high-tech optical sensor and a digital signal processor (DSP.) As you move the mouse across a surface, the optical sensor detects the movements and sends the information to the DSP, which, in turn, sends it to t
he computer. Because there are no moving parts, dust accumulation and erratic movements are eradicated, ensuring that your mouse moves like it did when it was brand new ? no matter how long you go without cleaning it. Also, because it uses a sensor you can use the mouse on any surface, including your arm! However, Genius recommends that you do not use the mouse on glass, mirrored or uneven surfaces to prevent damage to the sensor. However, we did happen to notice that the mouse does not cope with very long, quick movements. For example, when you quickly move the mouse from one end of the screen to the other, it tends to ?flick off? in a completely different direction. However, with normal mouse movements this is not a concern. We rate this mouse quite highly ? 8 out of 10 in fact. One thing we didn?t like was the bundled software. We ended up uninstalling the software five minutes after we?d installed it. The software allows you to assign popular actions to the two thumb buttons on the mouse. However, it also takes away the functionality of the roller. Without the software installed, on Windows® XP, you can roll the roller forward and backward to move the on-screen document up and down, no matter what program you?re in. However, with the MouseMate software installed, to move the document you press the roller down, then move the whole mouse forward or backwards. This is very cumbersome. Secondly on Windows® XP, the EasyJump feature of the software simply does not work. And, even if you only purchase this mouse for the light-up thumb buttons ? consider it worthwhile and definitely value for money. You will have a mouse that will last for a long while to come.
