Important safety notes: do not attempt to open bottles if the device is malfunctioning, damaged, has been exposed to water, or if the buttons do not operate. Do not force the corkscrew or try to increase its operating speed. Make sure the internal battery is sufficiently charged before use. If the battery is depleted and the corkscrew becomes stuck before extracting the cork, do not force removal; charge the device and continue once it has sufficient power. Corkscrew
