Bests & Worsts Reviews from Amazon

Do NOT, I repeat do NOT buy this product. From the moment you open their App you are bombarded with add-on features, products, upgrades that clutter screens and make it almost impossible to use this app. Communication between the app and the device is also problematic--I had to unplug and plug the device multiple times to get the app to read the device. Although I was finally able to obtain a diagnostic code from my 2011 Jeep Wrangler; I cannot say with any certainty that the code I obtained is actually a valid code. With failed communications, cluttered/impossible to interpret screens this app/product is a complete failure. I would have given it zero stars if that were an option. Caveat Emptor. You have been warned. As a side note: the welcome email I received from the seller was full of grammatical errors--clearly an indication of how little this seller cares about its product or its customers.
