Go with Ray Wu. He is very good. Last order I had was 20 roll of WS2812B 4 rolls had failed chip in 1 colour did not work on 1 led. Ray replaced all 4 rolls with new ones at no cost to me and no questions asked. Just had to supply photo's. Would highly recommend him to everyone.
Welcome.
Go to the mini get everything sorted out then order. Don't end up like me. I thought i was on right path went to mini and changed everything for the better.
