Works well swift support – Drummer ITP - Rudiment Trainer Review

Great support after I had an issue after installing new iPhone. Deleting and reinstalling did the job. It works very good! I worked first 15 min a day and after 4 days I had my first results. Recommended for every drummer at any level who want a checkup and improve!!
