They are friendly. I do believe this service is very good for electronic music producers, for me however, I had a bad experience. I mixed 4 tracks with them and 3 of them turned out to be not good enough to upload cause of noises and clicks in the mix. I do not believe the technician cares about the end result, they care about the order getting finished ASAP. Which is understandable. I think we are an exception tho cause I see a lot of good reviews. We ended up wasting like $500 on tracks that we cant even upload cause of wierd clicking noises that dont exist in our exported files but came into the final mix after we sent them here. Idk, It did not feel like we were getting through with our critique. I am sorry
