Query: Makes all the difference in the world

I ordered the replacement kit after whining to my wife about the way the shaver was "pulling" on my whiskers. It was then that I realized I hadn't replaced the blades in well over a year. The blades and screen are very easy to replace and they restore the shaver back to new condition, as far as the shave is concerned. This shaver is not the best in the world, for sure, but if yours is getting a bit painful to shave with and you don't want to spend $100 for a new one, order the kit and you won't be sorry.
