The VNsky website looks very professional and Gavin Chang responded very quickly to my RFQ on 8 July 2016. Their prices were competitive and they advised they had stock, whereas my usual supplier were out of stock. They offered shipment with 4 days of receiving payment. I emailed them on 18 July to request an update on my order but got no reply. Further emails have also been ignored, as has a message sent via their website.
