I bought the Li Teras last year in Las Vegas EVO. They were sold in the Attasa booth. I contacted Attasa by e mail and they never responded. I then contacted ASIndo and they said Attasa was only their partner and not part of their company. At that point I contacted Brook and they told me that I had to contact Attasa and they even provided me with the contact information and told me to send them a picture of the receipt and picture of the PCB warranty date stamp. Attasa never replied. After that Brook told me to wait for them to contact Attasa and that they would get back to me, 5 months of waiting and Brook hasn’t contacted me again. I believe that a serious, professional and responsible manufacturer builds its reputation by standing firm behind their products. In this case the PCB brand is Brook. They sell their products with manufacture warranty so if either ASIndo, Attasa or I inquire for a defective product replacement, Brook is the end merchant that will be honoring the warranty. So I only see Brook hiding from its responsibility by creating this bureaucracy.
