It arrived very well packaged and fast, in two days from payment. The pakaging is very careful and elegant and arrived almost without defects. The toothbrush has good material quality, the screen looks good but perhaps the sensitivity of the screen could be improved. The handle could be improved by making it less slippery, it already slipped into my first use. The app is very easy to sync and with many types of programs. The truth is, it encourages you to clean up better and get to areas where you lack continuity in cleaning. The travel housing has a nice design and even though it is plastic it seems durable though the area makes the game to open gives a sense of weakness. For now and despite small faults very happy with the purchase and I hope my dental cleaning will improve.
