I wouldn't bank on it working. Unless, you convince yourself that it is definitely going to work, and it becomes a tool to assist you. It is likely it will not be a miracle that launches you right away into projection. There are also lots of other tools/techniques out there, and you should find one that you feel comfortable with. As for anything going wrong, I've haven't heard anything negative about them, but anything is possible...so, be careful. Best of luck to you!
