Disadvantages:
-The LED the menu button seems hardly by and the function that these flashes is soon entered into a text message or you have missed a call, is to use under normal daylight barely. You have to look very closely to recognize the flashing.
-Yes NOW THE WORST:
On the envelope every speck of dust and every bit of dirt sticks soforf. If you pick up the phone out of your pocket or a matching cell phone on a belt is the Silicone Case dirket full of dust. Even if you have stores it somewhere you then guaranteed stick something on the silicone sleeve.
I no longer use this envelope now.
I found it just too annoying to constantly get the N8 from the casing in order to then clean again with water.
