Is this some kind of joke? I thought this is official forum with proper customer service. After few weeks I'm receiving reply asking to send an email to some guy, without any explanation who is that person. What's next? Will you give me a phone number to your factory in China and tell me to call them to speak with your engineer? Never seen such a poor customer service. You know what, I can't be bothered anymore. I'm done with your products and I will do everything to let my family and frineds know what kind of company you are.
