horrible, they are manipulative.. offer a free mastering to get you excited but once you get going you notice the limitations of controlling the master settings which are comprised of presets that wont automatically work for every song. Once you realize these limitations this service becomes useless. Their paid options are: either yearly at $156 OR monthly at $19/ month. The catch is if you choose to pay monthly you are obligated to use the service for 12months (I wish I could screenshot the site where it says this as it is completely cut off and you wont notice it at all). I only needed it for 2-3 months for a client but I realized this service sucks after 3 months and asked for refund only for the previous month, which they denied stating that they cant refund until the entire 12 months have gone by. Please tell me where else this makes sense in the world? So if your reading this stay away unless you are willing to deal with them for at least 12 months. Ive instructed my bank to not process any of their transactions
