As a HeadBlade fan, I will be a bit disappointed if I had to replace it after a year. I cannot see such a simple device wearing to the point where it must be replaced after even a few years. If mine does wear too fast, I would probably replace it with another, that’s how much I enjoy this little contraption.
I replaced my FIRST HeadBlade at about the three year mark...... because I left it in a hotel room shower. Change your adapter every 3-6 months and you'll be good to go.
Never really gave it any thought...but yeah, the plastic adapter is flimsy from jump (broke a few just changing blades) so that would be the only thing you would have to replace.
