The app is really good, Putpat.TV still know from my old Smart TV. However, every now and again to short dropouts in the Fire TV Stick. The video then hold for about 3 or 4 seconds, which is annoying in the long run fairly and reduces the fun. At my internet connection it is quite certainly not in Prime Instant Video or YouTube, there is no such dropouts.
UPDATE: Meanwhile, I've noticed that some videos always stop at the exact same spot that can not be an accident. So you should fix that please with an update, and it would be nice if it were not always pop up in the ad title of a song the lower menu.
