Hey,
I also have the "problem" that I have to go over the same spot 2-3 times for a nice even shave. But I think that's normal, or rather I've had the same problem with all my shavers. What was it like with the Philips bt5270?
As far as the redness is concerned, you really have to make sure that you don't press the attachments into the skin too much, as they are relatively angular in shape.
I hope this helps you a bit ;)
