I have two older Braun shavers, a 5610 and 7505, and got the 790cc-4 for Christmas this year. I'd researched the product and found that it got consistently high reviews, so I expected an improvement over my 7505. Sadly, this model isn't much better in terms of shave quality. The first shave was phenomenal- comfortable and close, with no irritation at all. Unfortunately, it was downhill from there. The shave was still comfortable, but it didn't last any longer than the shave I get from the ten-year-old 7505. This was a big disappointment considering the prices these shavers sell for. The cleaning base, while convenient, is way too loud, especially in the early morning hours. Just like the older models, this shaver had trouble getting the last few hairs on my neck, and the sideburn trimmer is actually a step backward. It's hard to see and awkward to use, so awkward that I only used it once. After two weeks of use, which I feel is more than enough to "adjust", I returned it for a refund.
In my opinion, for all the hype this shaver gets and for the prices it sells for, this model is a huge disappointment from Braun. I certainly expected more, but it appears that beyond the cool looks, not much progress has been made in ten years. I can't recommend this one.
