I got off the phone with handset now for over 1.5 years. The sound quality is inferior to that of old handsets. I find that embarrassing in light of technological progress. If, on listening, tear every now and then phrases, so that the other person does not understand some words. The handset appears to have a defect, because after half an hour call it simply switches off without notice. Despite newly purchased battery! The seller pretends to be dead. At my request simply comes no reaction. Amazon has written to him - nothing. So hands off!
