Poor after sales service, poor quality, buy at own risk
cannot be worst. Beside the low-level quality of their products, dealing with their customer service is daunting and frustrating. They don't read email but just reply with copy/paste emails. The after sales understanding of English is poor or their staff have serious understanding disfunctions. Or it is their policy to drive nuts the client so to give up. No spare parts available in case of need. No insight tech info of their products. I was asking the pinout diagram of a specific product, due to a lost RCA cable: it ended after 5 days lost in ping-pong nonsense emails from their side and their incapability to respond, with no idea from their side what a pinout diagram is !!! Basically, buy at your own risk.
