Very bad quality
1. First toothbrush (IO 6), loved it, brushing felt really good. Expensive heads but ok, now I can’t go back to something else. But… it died after 2,5 years. Could not get it back to life. 2. Second toothbrush (again IO 6), still loved it, broke down within 1 year. Unfixable damage (water I think). 3. My wifes toothbrush (IO 3), bought in January 2026, broke down within 6 months. Does not charge anymore. Very crappy quality and very expensive brush heads. Feels like they break down fast so they can get their recurring revenue. Looking for higher quality alternatives, because expensive, that it already was…
