This sonic toothbrush has all the features you would expect. Dressing excellent when used correctly, every dentist is looking forward. The unit has what it takes, no-frills. The price is therefore great, so affordable. The unit preserved this long. Please do not constantly reload, the harm to the battery! Charger just stuck to the grid if needed! Saves energy and triples the lifetime of the battery. The replacement brushes are very good in quality and function, hold almost half a year, are inexpensive to reorder. A small drawback. It lacks an LED to indicate the battery charge. This is nothing Expensive would be to wish well and costs very little money. If you know when the battery is fully charged, you can disconnect the adapter from the AC. So one has to do to suspect goes on, but it is annoying.
