Review on Rustic 12-Inch Waterproof Wall Clock - Silent, Non-Ticking with Thermometer - Perfect for Indoors and Outdoors - Battery Operated Retro Round Clock for Patio or Home Décor by Jeff Jackson

We've had them for about a month. I have it hanging on a vinyl wall behind my house. It is in no way protected from the elements. A tropical storm hit the weekend and it rained for over 12 hours straight. The clock works great. We have this to see times while using the pool. Our pool is about 50 feet from the house and the clock face and numbers are large enough to be easily read from a distance. I didn't pay much attention to the temperature sensor, so I can't comment on how well it works. The clock tells the time and works well for us. We are happy with that.
