Collecting is my all time favorite. That's the reason why I would choose something unlimitedly and Appsumo is definitely one of the best choices to collecting videos from youtube and paste to my website and arrange them my way.

Watching experience is good, the loading time is quite slowed than normal but acceptable.
I write this review on the last minutes of the sale, after spending 2 hours to test the app. I wish Killer Player will live long to support the community.
