That does not look comfortable to use at all.i would hate to spend that sort of dough and then find that prolonged use was not unpleasant.I can see that you can adapt it to suite but I think I would like to try before I buy.
I was looking for a gaming mouse the other day (click here). The RAT9 was one of the options, although ludicrously over budget. I wonder how much mouse you actually get for that money?! Didn't order it in the end, I went for the recommended Logitech Performance MX.
