Kliara has the fastest motor available, 48,000 strokes per minute. Just because your toothbrush has a battery doesn’t mean it’s a better brush. You need sonic speeds to get a deeper clean, to remove stains and plaque especially from those hard to reach areas. Kiara’s superior technology gives you the same fresh clean feeling you get from the dentist’s office but from home. Kliara is a slim, lightweight (you won’t believe there is a powerful motor inside), chic and quiet toothbrush. The best investment you will make in your smile.
