Overall, this app works very well! No stuttering issues or quality issues, and videos load quickly.
However, it has a number of irritations, the most obvious of which is the autoplay, which wouldn't be a issue at all--if you could turn it off, anyway.
The biggest issue, however, are the ads. This app will play ads--not even video ads, just the banners at the bottom of the screen--that play repetitive sounds constantly, and never mute, even when a video is playing. The popup video ads aren't an issue, but sometimes you'll select a video and a video ad will play instead, and once it ends, it moves to the the next video on the list without you ever having seen the one you wanted to watch.
These, of course, could be alleviated by paying to remove these intrusive advertisements--if the option existed for US customers. The developer never added the "remove ads" option for American users, so not only can I not support the developer, I can't even get rid of these advertisements that are making the use of this app more of an annoyance than it needs to be.
