Mine has not worked more times then it has.
So much for paying the price premium for a USA version and a paid subscription
Each time I try to use this scan tool and it gives me a backup error. I get more frustrated with this brand and the lack of support from Autel especially on. USA model and subscription.
Might just have to purchase one of those Chinese models off of Amazon. Because that has been my workaround is to borrow one of those every time.
