Excellent training aid
And I say training aid because this will aid in the training you should already be receiving. If you dont train, you wont learn anything from watching videos. You need to have good understanding of the basics first in order for any sort of video to be useful. But as for the videos in this app, techniques are great and production quality is outstanding. Definitely recommend this to up your BJJ game.
