Has anyone used the autel 906 scanner? I was kind of concerned of the support issues I have read. Supposedly they are all made in China but some have a usa serial number and the others are China units. The company doesnt support the chinese ones in the usa so you have to call China. From what I understand Amazon purchases will get you a chinese unit that will not be supported in USA? Anyone on here have any intel on this? Are the scanners pretty solid or are there better options out there?
