Question about Braun Series 5

Unfortunately, I can't give you an answer to your question other than to search for the different types on Google and find out the difference yourself,
I only bought my razors because I had to go into hospital and then into rehabilitation. I didn't care which type it was.
At home, I only shave wet and with a blade.
Good luck with your research.

According to our information, this is effectively just the colour.

Sorry, I can't answer that because I don't know it myself
