Review on Wireless Doorbell Chime - AVANTEK Mini Waterproof, 1000 Feet Range, 52 Melodies & 5 Volume Levels With LED Flash by Brian Buck

It's very easy to install, took me all of 30 seconds. I bought it for the after school program that I supervise and the kids often change the tone, making me wish there weren't so many tone options. Because of the nature of my program, we have parents ringing the doorbell every other minute for the entire length of our three hour program. So hearing that damn chicken over and over and over again gets REALLY annoying. The kids don't mess with it much anymore because it got too annoying, now we leave it on the traditional ding. But I wish there was a way to prevent them from changing the tone/volume at all. Or at least a way to lock the volume and tone so it can't be changed from the hardware itself. Like maybe an app?
