Instructions are a little vague but it's easy enough to figure out. It worked well and has more functions than I realized when I ordered it. Arrived quickly and overall it's an excellent product.

    • Good scanner for the price.
While this scanner feels a little light and I really don't want to drop it, it is a huge step up from my last scanner. It gives good quality reading of trouble codes. Vehicle specific. The live data is impressive. It can erase all the stored codes I have fixed. Well worth the cost.
