I have pleasant experience buying from Shenzhen Suns. They shipped quickly, and very responsive and provided accurate updates. Shipment to Malaysia reaches in just a few weeks with a door to door delivery. Equipment work great, as can be seen from the photos, in the midst of installation and already in operation.
