This was just what I needed to extend the life of my Remington shaver. The parts were easy to remove and replace. I can't say much about the shaver/cleaning unit. This is just to keep you buying supplies and adding to Remmington's profits. The first shaver cleaning unit cracked and leaked cleaning fluid all over our counter top. The free replacement cleaner cracked, and did the same thing. So far, the shaver is running a year or so without the cleaning unit. The replacement screens and cutters will probably last longer than the shaver. Oh, and another thing, the shaver no longer recharges, and I have to use the cord. The battery only lasted a few years.
