Review on AVANTEK CB-21 Mini Waterproof Wireless Doorbell With 1000+ Feet Range, 2 Unique Remote Tones, 52 Melodies, CD-Quality Sound, And LED Flash by Haji Anderson

Bought this for my elderly neighbors whose doorbell went out. It was a snap to install and set up the chimes for each door. My neighbors had fun picking out which chimes they wanted out of the 50+ choices. Volume is great for them, since they are both a bit hard of hearing. They can hear the chime anywhere in their house, and because you can set different tones for each door, they know exactly which door to answer. They are thrilled with their new bell, and I am going to buy one for my home also!
