I first got the deal in 2016 as was struggling to get some good results from my shots. The amount of data that I downloaded that time was incredible, as was the quality of the courses. Since then I got the 2017 and 2018 editions, which grew in size and offer (and quality), while maintaining a reasonable price for any kind of pocket. The best part of it all? It's all for charity. The bad part? Once you missed it it is gone, forever. Will certainly get the 2019 edition, might learn something new or improve something I know already.
