A:AnswerThis comes with blades installed. But when you need to replace them it is really easy. The three replacement blades each come with the shield and you just open up the razor, turn the little lock to release the blades, pop the old ones out and put the new ones in their place. Very easy.
A:AnswerI haven't had any irritation issues, so haven't felt the need to try any pre-treatment. The shave I'm getting is what I expect from an electric shaver - not as close as a blade, but good enough.
A:AnswerPhillips Norelco 50/52 replacement heads are what Phillips recommends on their website for razers originally using the HQ8. If you look at the pictures of the shaving heads they have th same ratio of lift and cut openings for longer hair and round openings for shorter hair which gives you the close shave. I already bought from Best Buy online these heads and upon inspection they look exactly the same.
A:AnswerHello! You shouldn't have any issues charging this shaver on your travels as long as the voltage of the outlet you're plugging into doesn't exceed 240V. The voltage for this particular shaver is 100-240V.
A:AnswerAll razors come with a wall charger, you should ask the customer service folks at the Best Buy store where you purchased it and they are so nice and helpful they will get you one.
A:AnswerMy AT890 just died and I have a set of unused HQ8 blades. I called Phillips customer support (1-866-800-9311) and asked what models are compatible with the HQ8 blades. I was told the HQ8 blades work with the Norelco 4100 - model AT810.
