"The irocks K71R keyboard features vivid RGB lighting effects. The wireless connection works as it should, although you have to be careful not to lose the included USB dongle as there are no storage options for it. The battery life is solid even in standby, offering approximately 27 hours of battery life with full RGB lighting at normal brightness. This increases to ~40 hours with the only key lighting on at normal brightness, all the way up to ~180 hours without any lighting turned on."
