Review on AVANTEK Mini Waterproof Wireless Doorbell Chime - Operating at 1000 Feet with 52 Melodies, 5 Volume Levels & LED Flash by Pete Deutsch

I thought it was good that there were two bells in this set, so I could put one on each floor. Calls plug and play. The bell button came with adhesive, was easy to install and seems to stay in place. My front door is protected from the rain by a canopy so it doesn't get much bad weather. The only, but not unimportant disadvantage is the volume. Yes, it comes with a volume control (it seems to have 4 settings), but even the lowest volume is deafening. If you have people who sleep during the day or children who you sleep with, you don't need this article. But if you need a call you won't miss even with headphones on, then this is for you.
