This Is a great mouse it has a DPI of between 400 and 2000 so that you can select
you mouse speed exactly like you would like it, I have one of these mouse's myself, loving it al the way and let me tell you it is a very comfortable mouse, not too heavy or too light plus you can add or remove weight from it, if your are on the look for a new mouse this is a great mouse and if mine breaks I would buy exactly the same one without thinking twice.
