Have I bought these cartridges for the cleaning station of the Philips Wet & Dry shaver series 9000. You can very easily change and 1 cartridge lasts me about 10 weeks of daily use. The 3 cartridges hold accordingly acc.Manufacturer about 9 months, and I rather. 7 - guess 8 months. The product itself is well thought out and also by building and construction. Nevertheless, I find the value for money considered as a whole only moderately since 1 cartridge, on average, approximately 7 - 8 euro cost (average price on the Internet.). When the cartridges are empty, for you. B. are still ways to flush the cartridge clean under water and then with a hand disinfectant (costs about 4.75 euros for 500 ml) to refill again.
I forgive Deshalt 4 stars because the product is very good in itself; 1 star deduction for the value for money.
