Positive Grid US

Worst customer service and technical support. Takes days to reply. If they somehow reply the content of their reply they sent you is a genric message like an auto reply. . what a waste

Send wrong merchandise no response to my inquiries love the amp, but having problems with the grill

Won't honor their own refund policy

I’ve spent weeks going back and forth with Michael. He keeps offering non-existent or inadequate “solutions” to my problem. What should really happen is that you should update Bias Amp 2 for the current Apple processors - they’ve been used for over 3 years. Instead, you keep making excuses, blaming me, and offering these silly “fixes” that don’t work.

Positive grid sucks
