This weather station is well built and a good price for an entry level system. The screen works great and is bright and easy to read.

Upon opening, the unit was basically pre-assembled, and just needed pairing and mounting.

Pairing of the screen and the unit was automatic and nearly instantaneous.

Installing the app was easy, but despite following the instructions, the app was tough to set up. The link in the app to the Wunderground page was dead, and there were numerous features that you can't get to in the app (ex: indoor temperature). I finally was able to get things set up correctly, but took trial/error, and once connected to Wunderground, you have to wait quite a bit of time before the data is available. Also, don't edit/rename your station, because this disconnects it. I thought I could rename it and it would update my display but not the Wunderground, and ended up having to rename it back.

Overall, only a couple days of use so far, but I like it. But the app is bad and desperately needs an update and a better UI screen. My recommendation would be to make the app look just like the UI of the screen that comes with the weather station.
