It does what it says it will, it does it well, and I'm happy!
I've owned two Braun razors that use the Clean & Renew system. I have loved both of those razors, but that being said, with this being a review of the Clean and Renew system and not one for the razors, it works just like it says it will. It does a great job of removing previous debris and hair and you get a slightly chemical smelling razor after a cleaning cycle. You do know it's clean, though, and that's a good feeling when you pick up your razor. I was pleased to find that with the newer Braun razors like the 790cc (as opposed to my 7000 series Braun that I purchased 10 years ago), it uses far less cleaning solution than it did in the past. This makes for the cost of keeping the razor clean much less. When I bought my 790cc razor, the first Clean & Renew cartridge lasted for almost three months with 5-day a week use. I was absolutely shocked at that and with Amazon's good pricing on multi-packs of these available, it makes the cost of keeping the razor working at it's peak condition very affordable compared to the 7000 Series which would use a cartridge about every 6 weeks or so.
