Most:
Very simple: on / off button, adjustable intensity, witness who appears if the skin can receive the flash button "trigger" on the handle to flash.
Large work surface, it will relatively quickly.
After a month the printing of "users" is that regrowth is already slower and sparser.
Long life of the lamp (15000 flashes).
Some notes:
We feel just a pinch "unpleasant" every flash, especially if the intensity is high, but it must be the price of success.
The size of the machine still important.
In fact the wire connecting the handle to the main body is just long enough to reach some areas.
The lamp is not easy to change (I wanted to try to remove / recover for the test) and I even bent a plug during operation, with a scare to the key.
Some have already indicated: it is noted that all must be very careful with sun exposure before / after, not to use the day to go to the beach so ...
In short, a very good product with only small flaws!
