not strident ????

it is ship, it's worth its price already received without battery and when focus stack, it does not work, I had to disassemble because contact with the battery was just moved, so finish reviewing.
shrill sound when pressing the keys to the discretion it missed
the bells are heard clearly even in another room (pitched at will but hey, it's well worth anyway)

Another strange point, it never goes off, I mean the display constantly something, What about the battery life ...

basically it works well and finish and workmanship are clearly bad, worth it for what
