Had expected from this gaming keyboard of Speedlink more. After six months, the space bar was broken. Thus, useless to play. A return to Amazon had not been possible for its provisions unfortunately. Therefore you referred me to the manufacturer Speedlink, which should now gestallten warranty processing. Made done! The manufacturer Speedlink referred me to my request, put back to the seller. ??? Great game. I think I can write off my money. At Amazon, I seem to have no other opportunities to exchange more or repair the defective part. Also ne mesh to make excuses for the warranty conditions.
