Underwhelming
Update rate is slow, not easy to program. Overall, not worth the cost as the Tempest app is immediate and up-to-date.

Will not update
I only have one app installed, the Tempest Weather Station app. Since I got it set up, it does not refresh the screen unless I manually press the button on the back for 3 seconds, and then most of the time not even then. I have had to reconnect to my wireless network, which worked for a day or so and then reverted back to not updating on the screen. When I look at the online app it shows it appears correctly, most of the time. This is not at all what I expected. It is not a monitor screen for Tempest at all. Throwing it in the trashcan most likely.

Too small to read on the wall
I guess I should have looked for a larger size for my kitchen wall. Also, I thought it would show the same data as I get on my phone Tempest app. Live and learn...
