That one is actually the grey rubber one, but I suppose it does look like white in a dark light. The cord is normally black, that cable is just a spare one the factory had, its a finalmouse cable. The factory said they don't want to make different coloured cables, I think they would if I had 1000 of each colour, but I don't. I would really love to use different coloured cables for each colour of mouse, because I agree with you it looks much nicer, but they are quite against it, I suppose I could have another go at asking them.
Thanks, thats much better
I tried it with 172 clicks, loaded them into excel and got an average of 5.64ms in favour of the Astrum.
