The Braun Series 7 7840s is a middle of the range Braun shaver. It doesn't have any bells and whistles like the more expensive models. The Series 7 does compete well with other brands in this range. I have used a Philips triple rotating heads shaver and I think the Series 7 does a better job. A closer shave at least. You are expected to change the head of the shaver every 2 years or so which does make it a more expensive upkeep.
