Review on Wireless Doorbell, PHYSEN Waterproof Door Bell Chime Kit Operating At 1300-Ft Range 58 Adjustable Melodies 5 Volume Levels & LED Flash, Doorbell Alarm For Home/Classroom, 2 Push Buttons+4 Receivers by Mike Pfettscher

So far so great! I have a doorbell on the house, on the gate for others and one in the barn and one in the bedroom loose to be by bed or bathtub to alert if needing help. Each has their own ring so we know who needs help or if someone is here and the ringtone says what location by which ring it has. It even has a ringtone that is an alarm! Only wish it had one more receiver for outside when in back yard! We have one in lr/ kitchen, one in bedroom, one in barn. So far the have stood up to the horrendous amount of rain we have gotten lately. Two of the doorbell buttons are exposed to the elements.
