    Disappointed with Serene innovations CA_CX

    Posted by Emilio Cortez on Sep 13th 2021

    The concept is good and needed. It's a shame that when you put your iPhone on the phone detector ringer--the sensitivity of the item is supposed to detect an incoming phone call, but even after physically shaking the item manually then and only did the lights and the ringer detect the in-coming call. I returned the item..
