Frequently Asked Questions

Our programs were developed by a group of former US Olympic Team Trainers. DunkNow LLC. is an established company in the state of California. We offer tours of our facility to our customers who are visiting Silicon Valley in northern California. DunkNow's products are also tested and proven by some of the strictest restrictions.
There are tens of other Vertical Jump programs available online but please be careful as many of them are scam and gimmicks. The majority of the scams include E-Books that are downloaded in a word document after purchase. These programs are home-made and put together very poorly.
