The contrast is really not as good as in the picture. Pressing solid, the writing is lighter, but it is thicker and feels a bit as if you write with ink on blotting paper. The "color" is not white but greenish. Using your finger man can not write really, more than a fingernail.
As long as you do not press too hard with the knuckles but you can therefore rely on the tray by hand during the writing. If you want to store it in your handbag you might have to buy the protective sheath to - if the mobile phone or similar on the other hand is the display in the bag is already full "written" - the lock button prevents the deletion, but not the letter.
