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. The sales representative (Amy) has provided good knowledge and helpful to guide me to make the purchase correctly. Thank you Amy and thank you Shenzhen Suns and this company is highly recommended!
