Summary: Easy,just charge overnight, place in master unit to key, id the hadset, and done. I particulrly like the intercom feature. We have one in every room in the house, with the exception of guest rooms. Sound quality is great!
Summary: added this handset to Vtech LS6475 3 w/ 2 Handset Cordless also bought through Walmart. The phone is great! The headset is excellent. I've experienced NO problems at all. Easy to set up (let them charge overnight). Great voice response, hearing caller, managing call. Does not have option for special ringtones, however, it announces caller so when you are using the headset you don't have to visibly check caller id. Adjustable volume.
