Purchased this as a backup tool for a professional repair shop. We typically use an Autel professional scanner. We purchased the Mucar as a backup for when the Autel was in use by another technician. This scanner blew us away with its capabilities. It does far more than it's price point would suggest. On top of that it has free lifetime updates, which is a huge cost savings over the life of the scanner. The techs are now grabbing this one first more often than not, as they say it's easier to navigate than the Autel and can communicate just as quickly. There are things that each scanner does better than the other, but overall this scanner is very impressive for the cost. We'll see what the long term durability is, but so far it feels well built and has been used daily. The battery life has been very good and it charges with a regular USB cable, which is handy. I do wish that it had a charging cradle, but that's a minor complaint since the battery life is so good. Haven't tried any of the accessories yet, but we may buy some to evaluate.
