Goodies: very easy and intuitive transfer the entire directory to other handsets and customizable ringtones. Moreover, I very easily apparaillé a handset of another brand which allowed me to benefit an additional handset installed in the basement. The combined background colors change basic products. The tones are soft, In the early days of use, I admit I sometimes forget that the phone rang. Matter of habit. Product cheaper than in large stores and no shipping costs (amazon) is a criterion to be taken into account. Fully satisfied with the product after more than a month of use.
