Negative Positive
Title: Disappointed
Review: I was really excited to get this gadget. Unfortunately it did not work for me. When I tried to see the average MPG, the numbers being displayed every 2 seconds were absolutely random: 31.5, 91.2, 28.4, 75.2.....and so on. Then I tried to get data for a trip; the gauge started recoring and after 3 seconds it stopped. When I pulled over and looked at the dial it had NO DATA... I tried to measure it several times....no luck. Bummer! I drive a 2007 Nissan Sentra. I wish this item would have worked. Amazon.com does not have exchanges on this item, so I just did a return for a fuill refund. Will not try my luck and purchase a new unit.
