Review title: This thing works, period!!!!
Product review: I am not a handy person and do not like to read through the manual. I even called the help line after I received the product and read the manual a couple of times (even though I do not like it). I never repair my car myself and do not plan to do it. However, I would like to know what is wrong with my car when the check engine light is on before I take it to the dealership. I just want to be safe by not ignoring serious problems.This thing works perfectly. The most difficult part of using this tool is to bend down and hook it up (no need to use any other tools). The rest will take about 2 minutes. So far (since Friday), I have canceled 3 lights (98 nissan, 02 VW Golf - twice, 01 Toyota Corrola with a rebuilt 02 engine). None of those car have serious problems.
