Amazing support team
I purchased a GT6 Pro about a year ago. After using it for almost a year, I suddenly encountered a problem with no sound. After discussing it via email with the support team and attaching some data and videos, they confirmed a hardware problem with the sound system. Without further ado, the support team immediately offered to return the item for inspection and send me a new, sealed product. To date, the new product has been trouble-free and is still in good working order.
