I bought an FF AT board that broke down on the first day, and was then stolen by Maxfind...
I bought an FF AT board for $1000. Because of a faulty design, one side of the truck holding the motors simply separated on the first attempt using the e-brakes. It is all documented in a reddit post (search "how_a_manufacturer_designed_a_faulty_and") After weeks of emails and back and forth showing Maxfind the issue, they told me to send it back to a german location where they could fix it for me. I paid to ship it. At this point, it just needed the ESC replaced. After 5 months, and 75 emails where they kept telling me "next week we ship it back", I gave up. This was 9 months ago. So, they basically stole the board I bought from them... Avoid at all costs: the few $$ you save buying from them will be offset by time, effort and money. And in the worst case scenario, the board will injure like it almost did with me.
