Review on SadoTech Waterproof Wireless Doorbell: 1000 Ft Range, LED Flash, Battery Operated - Perfect For Home Use by Wilbert Luoma

This doorbell easily installed on my chain link gate with the included sticky pad. I placed the ringer on a plastic board and fastened the board against the fence. Most of the rings are digital music. There are eight "ring" options on this doorbell which was sufficient for our needs. The second loudest setting can be heard down the hallway through a closed door.Waterproofing is as advertised. I frequently water my bushes with the gate open, and the ringer gets drenched. It's also held up well in the southern California sun, with the battery lasting over 8 months already. You will have to unscrew the circuit board to get to the battery, which is going to be a pain when the battery needs replacement.Pay a little more to get the SadoTech. The cheaper models don't last.
