I used this phone regularly (about 20min / day) for 2 years. Sound quality is flawless, and it is really class blue. I want to clarify that you can activate silent mode by holding down # if I remember correctly. The black spot is autonomy. After two years of regular use, the battery no longer holds the load, and I am obliged to call, leaving the phone on its base. In fact, I feel that this is the backlight that pumps a lot of battery.
