Super fast delivery and it was so easy to set up the unit. It literally only a minute to set it up. And so easy to add it only multiple devices. Both my husband and I monitor on our phones and we have set it up on an iPad for the grand mother's to use when they are over to baby sit. Only concern is about the security, of it can be hacked. But reading the ibaby website it sounds fairly secure and just requires frequent password changes and should be fine. Love the features to be able listen and speak and the notification. And be able to turn these features on and off as needed. I've pretty good product for the price you pay.
