I'm sure everyone has his own opinion, but here's why I bought an Autel, new open box for $699. Customer service and quality. I was familiar with Autel's automotive diagnostic tools. I felt they had lots of experience getting good quality from Chinese manufacturers, which is the failing of most importers. Autel's customer service is excellent. I was burned good by Upair and their non-existence of even an email address or parts. Reading forums, I found lots of criticism of Phantom's service. I also found very little criticism of Autel's product.
Since I got the XSP, it has behaved exactly as it should. No surprises. It's well made, stable and reliable. It's the rare product that I have purchased that has given me 110% satisfaction in deliving quality and dependability.
The only shortcoming is the lack of aftermarket applications, if you need that. But Autel has just made their codes available to developers, so that should improve. For now, I'm fine with Autel and I feel safer as a beginner with their American-based resources for owners.
