As a forty something gamer, I have used and keep searcing for a good mouse. Like many left handers, finding a comfortable gaming mouse is quite tricky. The plus points are as follows - good balance and weight, very precise, the packaging is overdone.
The negatives are - the scroll wheel clicks (more like jumps) so not good for gamers who prefer a smooth scroll wheel, the buttons on the right of the mouse are not recognised by many games, as you insert the mouse you have to hold down buttons for left handed configuration, however, this means that when you use windows the buttons become transposed - left is right and right is left which is annoying, changing dpi is fiddly. There is no mouse driver so no configuration at the software level is possible. Changing dpi is also via series of holding down buttons which is not practical during games. As the other review states - compatibility issues - running XP with SP3 the mouse is not recognised at boot up - you have to unplug it and plug it in again - no drivers to update so this is very annoying.
All in all disappointed, I would not class this a true left handed mouse - more of a an ambidextrous option. I will stick with my Trust Predator for now and keep searching and keep paying.
