Philips 9000 Series Shaver

I have been using the Philips 9000 series for several years, and I am quite satisfied with how smooth and effective the shave is. It is good enough to justify the high price, but since I cannot replace it frequently, I have to take good care of the device. I use SmartClean for maintenance, but it breaks down more easily than the shaver, so I have purchased a second one. The cost of the device is more than the cost of the product itself.
