I have used this to watch over the air tv from a rural location. Tablo works for me, though it has been far from perfect. At one time, a certain station was not viewable, but the others were. This seems to have resolved itself, not sure if it was an app problem or a device problem (as the device has had firmware upgraded multiple times since, and the problem has not re-occured.
The reason I only give this 3 stars is because of:
1. You can’t switch away from Tablo and have the video collapse to the thumbnail, which you get from about every streaming video app.
2. related to this, it doesn’t even keep the audio going if you switch away from the full screen video. So there is no way to switch to a different app while you wait for the weather or sports in a newscast, for example.
I haven’t tested the recording and playback enough to evaluate it.
As far as the device, if I realized it didn’t support streaming to windows devices, I probably wouldn’t have bought it. Otherwise, it seems functional.
