Product review (4 stars): Works great out of the box!
I needed a new weather station- the old one was starting to malfunction and I had become adjusted to having basic weather info at my fingertips. After much searching, I decided on the WX-11, because it showed a lot of data, it was colorful, and I could use a pool temperature sensor with it (purchased separately.) Everything was packed well and the instructions were easy to follow. I had both sensors up and running in just a few minutes. The numbers are big and easy to read, and I am waiting to see if the colors are helpful or a gimmick. I'm very happy I purchased this, but have two cons, one small and one larger.

The first has already been mentioned, but the company does not send a screw with the outdoor sensor. After some rummaging around, I found one that will make do, but it's a curious omission. The second and more serious complaint is the AC cord. I assumed it would be at the bottom or the back of the unit, but instead, it's on the side, making it pretty much impossible to hide. This clumsy engineering is the only real issue I have- other than that, works great!
