In my studio, it did exactly what I needed it to do, and I can confidently recommend it. However, you need to know what this is for, I'm not a sound engineer, but this is what I've gathered from a month of looking at tons of videos and reading tons of forums to learn how to sound treat my studio. Also, English is my second language but I'll do my best to explain this clearly.
