I bought my Philips hairdryer in 1994, for my son to take to college (it only worked when you held it, and cut out when you put it down, brilliant technology for a student!)
Since about 2008, when my own hairdryer broke, I have been using the little Philips hairdryer myself, on average 3 times a week, including this morning.
I think it might be getting tired😥 as sometimes it slows down when using it.
well done Philips
