I was told that you can use shaving cream with the Bruan Series 7 but can't find supporting documentation anywhere. The sales person said that they also recommend it. I hate that I was sold on this fact - even though the shaver is good, and want to make sure their statement is not false. It is a legitimate store and I bought it based on their recommendations on what the shaver can do.
Welcome, of course, but I'm not sure that most of us know anything about electric razors. I have read about this electric razor forum. Perhaps they can help you there.
