Received quickly, this toothbrush is well presented and of good quality, the first brushings surprise compared to traditional electric tooth brushes. But within days I really saw a difference on my dental hygiene, especially at the pie; the built-in timer is convenient as a bathroom we did not necessarily a pendulum to realize the brushing time. At first it seemed "long" and finally includes only 2 minutes of brushing is useful. I recommend it and would like the same with charger that's why I put 4 stars.
