"A little nervous from reviews BUT!!!!!"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I was a little nervous from reading some of the reviews on this thing for pc and in general to pay so much and have it “bug out” but, so far so good!!!. Installation was really easy, the way people made it seem for the install process had me prepared to be at my computer in the setting tab changing different audio files lol. Sound is amazing!! I thought maybe everyone was overdoing the sound quality that this has but they were not, it was great lol. I would say if you have a pc with usb 3.0 built in then go for it, it’s the industry standard in audio interfaces, but make sure you computer or laptop is up to par so it won’t give you any installation issues. But don’t let the negative reviews scare you off of this thing it’s great and zZounds have great payment plans to get it to you the next day.
