1005 recomended easy to use and great quality of sound nothing to dislike will recommend to others brought this because it was light weight to use around the house as my wife has a disability and thought this would make life easier sadly this is not true the vox function is intermittent and my wife thinks she has called me but i dont receive the call the manual says there is a qt and dqt function it tells you what it is but not how to set it up if its needed and finally the battery life is very poor it has been charged several times but still only lasts a few hours would not want to go out of the house for any length of time
