I just got this mouse today, the first Logitech mouse with MX technology.
It is amazing. doesn't matter how hard I try to sake the mose cursor around, I can't seem to shake it off track. unlike my first logitech optical mouse, the cursor go like crazy after some violent moves. this mouse is just amazing (and nice looking too)
for all the gamer there, I must say, if you haven't get this mouse, this is a must get.
