Broke in 4 months
I chose this toothbrush after my basic Oral B electric toothbrush finally wore down after a few years. Figured it was somehow 'better' since it was 'professional' and 'deluxe.' This toothbrush short-circuited after about 4 months. Water somehow gets into the battery (from the top or bottom, who knows), rendering it useless...until it dries, then it becomes schizophrenic and turns on at random times. It finally lost all ability to recharge....waste of money. Buy the basic one, they all use the same brush heads, so you get the same clean.
