Fast, courteous, effective. Their main assets are the software itself and the service, which is fast, courteous, and effective. Who can ask for more?

Not all it's cracked up to be I cannot change YouTube accounts no matter what I do. I log out, but when I try to log in it automatically logs in to the account I just logged out from. I have reached out to customer service with no response.

4K Saves the Day I'm a old school DJ, 4K downloader allows me to get the music and videos I want. I have an extensive music catalog and I'm missing some titles that are no longer available anywhere except on YouTube. And there's no copyright infringement! This app is invaluable to me and extremely useful. I've used many apps of this type and none of them are still around. 4K saves the Day😂

does not work after... (last update?) It used to be good but since last update I could not start it at all. A big disappointment since I use this app very much. My initial review was rather negative. But after that review, tried several times to download and install again. At the last try, it somehow "repaired itself" so is working fine again. So honestly have to say that the app repaired itself and that is an effort I appreciate.

only the designated sound source is fixed and downloaded. This is really the perfect video downloader. It's the simplest and most necessary function I've ever used. The only regrettable thing is that only the designated sound source is fixed and downloaded because it is impossible to change the sound source.
