I was just wondering if anybody has used the 60mm v-band wastegate that ssautochrome offers on ebay?? How does it compare with the HKS style 50mm??

Here is a link to the style im talking about

Please dont turn this into a quality control battle over buying from ebay. I just want to know if anybody has used this product and if they have, how well did it work??
