Three corkscrews very aesthetic delivered Lacor, both are not working. After initial charge recommended 10 hours, nothing happens ... The battery is not charged (malfunction). I wanted to offer this evening December 24 at buddies ... It missed ... But these are buddies and they will understand, I will open them a bottle 'champagne' that does not require this tool .. .The third corkscrew runs but the engine torque to the worm to uncork the bottle seems very low. If within a month it does not satisfy me I ask for a refund. Purchase inadvisable. ..
