Original Xiaomi Mijia Doctor B Youth version BET Toothbrush.
This toothbrush is so soft and pleasant to use, that I have decided to buy one more of them. The first specimen I have received as a gift with a purchase of an item that I can not remember what was. Indeed it was a good policy, because addicted me. I do not know if they last at least three months but I hope so. The price can not be considered cheap but I understand that it worth. Due to epidemic issues, the initial shipping was very low, what is partially accepted. Seller’s support could be better, providing a proactive support.
