Review on AVANTEK Wireless Doorbell: 1300Ft Range, 52 Melodies, 5 Volumes & LED Flash - Waterproof Chime Kit by Christopher Cortez

Works well I'm using one doorbell on my front gate about 40' to the nearest receiver and the 2nd doorbell on my business front door both work most of the time. I think some customers might not hold the button in quite long enough? I have 3 receivers 1 in the front of my shop, one in the back of my shop and one in my home next door. The only Issue i find is that the bell ringing has low volume. my hearing is poor but If I'm not within 20' direct line of site I can't hear them just one wall between me and the receiver and I don't hear it.i have had these for a couple of months now, both doorbells are out in the full sun, rain, snow and then continue to work so the waterproof seems to be true. I'll revisit this review in the future if they fail or after a year or so and they are still working
