Panasonic EW-DL22 Main unit and charging stand - Model Name: EW-DL22 - Brand: Panasonic - Color: Pearl White - Included: Charging stand and cover I think it's been about 10 years since I bought it. The sonic vibration wasn't very strong, so I stopped using it. I think I only used it for about a month. I don't know the lifespan of the lithium-ion battery, but I have confirmed it works for 3 minutes after a full charge. Box and replacement brush heads are not included. Please comment if you have any questions. I'm selling it at a low price, so please understand that it is a used item before purchasing.
