I absolutely love this product, it cuts better then a cutter my wife got from a professional store. The only thing I would like to see is a stand or holder of some sort, that way I don't have to lay the shaver down. If the stand or holder charged the unit that would be a bonus but not necessary.
I am a mostly bald headed, head shaver. I have some fuzz on top and relatively normal hair around the sides of my head. I occasionally don't feel like shaving for a week or two and this razor is great because when I do that I no longer have to pull out the bulky hair trimmers to get my head hair down to a manageable level, in fact this product cuts close enough I can go a couple days after using this product without shaving, which reduces irritation. I took one star from Performance because this product struggles with the fine fuzz on top of my head, particularly when using it wet. I took another star because the little part in the head that spins to make the cutting head cut can get pretty clogged up even with a single pass on the sides (even when hair is not very long). Those two starts from performance made the overall rating 4 but I really do like/borderline love this product!
Pros: size convenience
Cons: heads get clogged up easily (see full review), struggles with fine hairs
Superior to any method of shaving I have used so far. Gives me smoothness close to a razor, whether shaving the face, neck, head or body, including below the belt, with no nicks, cuts or ingrown hairs. A battery charge last for weeks, usually.
Now the issues: first, the replaceable shaving head itself is a precision piece, easily damaged and must be protected from being bumped around in a travel kit. Philips did provide a cover to help resolve this, contact them if you did not get one in your package.
Second, when traveling it is very easy for the power switch to be bumped and turn on. I learned this while going through airport security, when I had to fish my shaving kit out of my carry on to find the source of a humming noise. A travel lock of some sort would both avoid this and let me leave the charger at home for most trips.
Pros: helps me get smooth all over with no nicks
Cons: blades don't last forever
Close
Blade is easily damaged by a minor bump, but still works.
Still learning the best way to use the trimmer. However, I no longer use my rotary razor. One blade shaves and trims. The shave is close and the trimming makes clean lines. Never had facial hair before. I have been using it for only a month. If any thing changes, I will give another rating.
Pros: cost and compact size.
Cons: off button is in wrong spot. keep turning it off.
