Prefer battery powered Sonicare toothbrush over plug-in easy to store away and travel. Can store away in cabinet when not in use. Been using Sonicare for years per my dentist recommendation. Better for gum and tooth care.
Excellent, natural brushing action. The life of the battery and the brush head are both very good. Of the inexpensive electric brushes I have owned (about 3 or 4) this is the best - have had it about 3 or 4 hears without any problems.
