like the fact there were two units. I keep one set up for my grandbaby and one in my husbands work shop. I live in a 3 story home and have arthritis, this saves me from climbing steps to call my husband, I can talk to him on one unit and keep an eye on baby with the other.They are easy to switch back and forth. If baby is fussing can talk to him and calm him down.
