Query: outdoors sensor isn't for outdoors,. also weak range

I have had this a week and it is useless. The range was about 25' through a wall, and didnt read the outdoor meter. That makes it close to useless.It rained for the first time yesterday, and the outdoor sensor got wet and it is now completely useless.What's the point of an outdoor sensor that cant take rain? If I wanted to walk out and look at a thermometer, I wouldn't need a wireless one.There are a lot of "should be great" pool toys/lights/thermometers that are poorly made, this is the next in that list. I have looked at the comparable items, and there are none under $200 that will work. I should have regarded more of the negative reviews on this one before buying.
