I higly doubt this device will help.
I have been an amateur broodwar competitor for many years, and each progamer that I have met plays differently. In fact, most progamers that are very successfull are those that have different styles from other gamers, and can make it work well. This means, trying to use a device to emulate a progamer wont work in this form.
Any progamer knows that its not the gear that makes you a progamer (assuming minimum standards are covered) but years of hard work and practice.
That beeing said, I do love steelseries mecanical keyboards.
