I had to get a new GHD iron last week - simply because my old one does not work when I travel to the USA. The older versions were simply not dual voltage. However, I still use the old one most of the time when I'm in the UK.
I checked when I got my old one - and was a little surprised. It's over 7 years old now. Yeah, I know that things should last long, but I was seriously surprised it's still going. I know we live in a buy and throw society, so may have gotten used to things not working longer than the warranty allows…
How old is yours?
