I used for years an Oral-B, to this eventually "weak chest" was. Now nobody is buying a new battery. So I compared different types. There are indeed cheaper, but because of the durability and the good experience I decided again for Oral-B. I have not looked back, and later published review (Stiftung Warentest) has confirmed my opinion. The charge indicator LED is no frills, but trains the battery (and save current). The "stutter" in automatic to firm pressure not only protects tooth enamel and meat, the expensive brush heads hold so long. One star deduction only because of the price.
