Installed without problems on XP. Very pleased with the purchase. Pros below: Very low price, waterproof, the kit comes with a bag that is necessary for gamers, the location of the keys also allows you to use it without problems. The appearance is strict, without any unnecessary frills. Some cons: There is no support under the hand, the hand still gets tired, unlike the Logitech device of the same kind (but I consider it inappropriate to overpay for the LCD). The style all the same from cheap material immediately betrays itself (but what I wanted for 375)
