I’ve used Indigo Mind Labs ‘Ultimate Monetary Success’, and honestly I think it was fairly effective for the time I used it but WAY too much time commitment for me at the time and caused headaches/lack of sleep. Other subliminals that require a lot of listening time (mindprolabs) are also effective, but I think much of that is due to how often you have to listen. There are much better ways to use your time for subconscious change.
Not to mention, I find subliminals that ask you to only use one for an extend period of time to be restrictive. However, consistency is key so it really boils down to what results you want and how willing you are to get them.
