I have a Braun Series 3 and after each use, I put the machine in the cleaning base. The result is always impeccable. The device smells nice and looks like new. Cleaning is done with a special liquid, thus avoiding irritation of the skin during shaving. The most economical purchase is the 5+1 package in terms of unit price.
With daily use, one cartridge lasts an average of 2 months. In the summer, because the product is alcohol-based, it evaporates faster. If you leave a cassette open in the machine and don't use it, the product will evaporate over time.
It may be an expensive product, but it takes good care of the machine and the face.
I can recommend it without hesitation!

The price of them should drop a little more, but other than that, I don't think there's anything else to say. A one-way street for self-cleaning BRAUN machines.

It is the second time I order this product from Greece and I have been very satisfied because you can't find it at this price in stores. As for the quality, as other consumers have mentioned, it is an excellent product and this helps the brand of the shaver, the liquid is in very good condition and you realize this with the uses you make. I highly recommend it.

There is nothing that you can consider negative about a liquid that cleans and disinfects the razor very well

Very good blades that leave a flawless skin during their use. The result of shaving is perfect! Great battery autonomy and beautiful design!
