EG Quick Tips

The great DPI debate... is uber high DPI needed or not? At the end of the day, this is dependent on what your needs are.

We recommend going with a mouse with a decent DPI rate complete with a control switch feature, which allows you to change between preset DPI rates, giving you the best of both worlds!
