Autel scanner warranties are not as they advertise, if you don't buy from an authorize seller. I made the mistake of buying on Amazon. I had to send my MS906BT scanner in for repairs and after 3 months they want $300 to replace it because they don't know how to repair it. Warranty says free replacement and nothing about a charge if you don't buy from one of their higher priced authorized sellers. I don't know what the difference is where you buy from because it's the same scanner from the same company. I think it's just a way to get more of your money. Needless to say I will never be purchasing an Autel product again.
