Equus 3130 Great price and performs

I bought this product because 2 Autozones couldn't read my error code with their Actron scanner. I hooked it up and it worked perfectly. Changed the O2 sensor and watched the screen for a couple of days until it had passed all tests. My vehicle passed the emissions test. Same with my son's vehicle. The unit is easy to read and understand. Software comes with it but I haven't tried it yet. This unit is a good buy.
