This is already the 3rd of Philips. Thankfully hand parts have gone nearly broken during the warranty period. Terribly it that obvious scrap is produced, which is to hold just over the warranty period. The batteries were hitherto never the problem. Am disappointed by the obvious planned obsolescence. In addition, manufacturers earn a fortune on the brushes. How are fair proves Aldi. Zahnschhallbürste: 17,95Euro including Ladesation and spare brush. 3 years warranty! In addition, there cost 6 brushes 3.99 euros. Philips: I have done!
