DUO JIE ELECTRONICS / Defective parts, no returns
This is a warning to everyone considering doing business with DUO JIE ELECTRONICS from Hong Kong, China.
The guys are not flat out crooks, but have extremely poor business procedures and QC resulting in terrible problems down the line.
We've been working with them for about 3-4 months and the first time they sent us bad parts they took them back, but the second time they took them back and we never saw any refund.
By this time we had already figured it wasn't worth to purchase their (otherwise cheaper) parts when you couldn't predict when and how much of them will be defective.
My advice to anyone is simply AVOID DUO JIE ELECTRONICS!
