If i could give less stars, i would. The worst investment I ever made. It looks cool, and pricing is great for initial purchase and updates but that's where it stops. Slow, clunkie and worthless. Iv been using various scan tools over my 31yrs as a tech and this is by far on my list of bad scan tools. BUT in its defense, it does have some pretty cool ad-dons. I purchased the Scope leads, Bore scope and charging system leads, All work well. Again, the updates are inexpensive and its better than a level 1 scanner.
