Query: Like having a new razor!

I'd been getting unhappy with my razor's performance, and then realized that I had *never* replaced the cutters in the 3 years I'd had it. Now it's back to doing the great job it used to do! An important bit of maintenance to remember if you have an electric razor--check the instructions to see how often you should replace these parts.
