Article has already convinced me of the box as it is processed. To my surprise, is also a pocket in the price available. Product is well made and has detected the error on the vehicle immediately. The article to my surprise was delivered very quickly. (2-3 days) It would not be bad to get a software where you could reset service intervals. Then it would be a good instrument for the price To criticize is that the software needs to be installed only on the included DVD on the PC. That's why only 4 instead of 5 stars
