I used since 2.5 years, Emmi dental. 6 The cleaning result is good, no question. It's just great pity that the processing is really deficient. My first Emmi fell apart after about nine months. The rubber on the sides went off like rolls of a pencil eraser. Did the complaining and get a new brush. In the second brush there was the same problem after a short time. I keep still and wrapped with Gaffaband. Now, however, is also technically Feierabend. My husband also has a Emmi. Its battery life was poor from the start. He needs every day laden.Das is not normal and was in my equipment different.
Conclusion: All three devices have either technical or processing technical quirks. I think that's really out of the question for such a price.
