i heard someone talking about fireglider..so here we are, some pictures of it..

for me, the ergonomics shape of the fireglider just fitted nice to my fingers and palm..although, it's a lil heavy and your wrist might get tired when you use it for the first time, you'll get used to it very fast..

the weight is doing fine with me currently with all the balls fitted in..as mentioned by ham_revilo, it's kinda troublesome if you wanna remove the weight from it. A small tiny pin will do the trick. However, it's advisable to be careful as it might scrathes the surface..At first i thought my mouse was the one having this problem of removing the back cover, however, after i tested another one, i found that it's the same..The only disadvantage i found so far is just the cover. Others are working fine with me..

my favourite part of this mouse is the rubberised area on the left hand side..it makes your thumb very comfortable when it's attached to. however, for the left click and right click area, i found that the surface gets dirty easily..eventhough, i wash my hands before touching it, the dirt will still be there after i finish using it.. all you have to do is to clean it up everytime you see the dirt

furthermore, i still cannot get used to the larger macro button on the left hand side of the mouse. i found it kinda hard for me to press that button with my thumb when i'm maneuvering my mouse maybe it will take some time to get adapted to it..

i dunno much about A4Tech, but for me this a money worthable mouse to be owned in terms of its dpi and if i'm not mistaken, it's a product from Germany..so if you wish to have an affordable laser gaming mouse with a high dpi, this mouse is one you have to go to..
