One item that has not been discussed fully so that a general consensus is reached, that being, which OBD-II product is better? Alex Peper's or Harrison's. Readers who have experience with either one can chime in as to their opinions as a user. Furthermore, I believe that this board would be highly interested in a reader who has experience or has used both of the products. Thanks to all for your response, as maybe we can delineate the differences for all to read.
