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

So far, so good. Easy installation and after a month, the doorbell still functions in heavy sun/heat. No rain yet to test it further. There are many bell choices and they were a bit tricky at first trying to get that set up but it is up and going now and working well.Update: the doorbell made it through several days of very heavy rain! The plastic piece on the bottom section was full of moisture and I was concerned that that would affect its performance - but no, all is still functioning well several weeks later.
