For how many washes can I run with one cartridge?

I get 40-50 days on ONE cartridge… how I does this simple… when I shave I shave every 2 days sometimes everyday BUT the key to making solution last is I ALWAYS and I mean ALWAYS rinse shaver under water and take cassette out and rinse that under water “probably 2 times” that way all the hairs DO NOT clog the machine AND it does not blacken cleaning solution or make it more dirty then it should be… then when solution gets down to half or about half (3-4 weeks later) I add “just alcohol” and fill it back to top … NO dumping or cleaning the solution out cause it doesn’t have much hair at all because of me cleaning razor under water after each use… my cleaning station is basically a station to sanitize my razor and get whatever tiny bit of hair is left over … that’s all it’s for… if you want t to shave and just throw it on cleaning station your solution will be gross after 3 weeks and you want be able to top it off also… 6 cartridges will last 10-12 months if you follow my steps and also your solution will remain clean enough that it won’t clog and break your cleaning station with in 5 years or so… also when you replace a cartridge in the station rinse it out and clean it like new every single time … it will last till razor completely dies if you take care of both products…

whats the difference in the Braun 7 790 and the 9 9370?

THE DIFFERENCE IS THE AMOUNT OF VIBRATIONS PER MINUTE THE SEVEN SERIES IS AROUND 25, 000 AND THIS 9,000 SERIES IS 40,000 PER MINUTE. THE NINE SERIES HAS FOUR SHAVING HEADS IN THE CARTRIDGE INCLUDING ONE TITANIUM HEAD. 9000 CAN BE USED IN THE SHOWER

Braun, any plans on an unscented formula?

Their default version is unscented. The lemon is new.

How to discard used solution?

I flush it down the drain. Don’t overthink it. That’s why I pay the big bucks for water and sewer service. There’s such a small amount of fluid by the time I discard a used cartridge that I don’t believe it’s a hazard. At least not to me. And I rinse the container and put it in the recycling bin. Buh bye!
