Bests & Worsts Reviews from Amazon

In my opinion most of this devices poor reviews come from the time when you had to pay for the app to activate features. Other reviews simply come from individuals not understanding OBII or how it basically functions. This app imo is awesome 1st I am a used car dealer I need a fast OBII that is accurate and that can do a basic scan of all vehicle to make sure the car can pass emissions and to check for trouble codes or pending codes when a check engine is not on. This does it plus so much more. Another import aspect is I need something small to carry around auctions. It gets tiring even carrying a small OBDII that has a cord. This is perfect it can fit in my front pocket & for rainy days I just toss it in a waterproof wristlet. Today I scanned about 50 cars nissan maximas/ altimas/quests/ muranos/ toyota siennas and prius honda accords, civics, odysseys, BMW 3 series 335 and 325, Porsche Boxster, VW Passats, Jetta, bugs/ Audi A4/ acura RSX and TL. Basically it scanned every car I needed it to. Now on some cars the extra features did not work but that is expected most handheld scanners cannot do certain advanced features unless you have a scanner specifically for Euro cars. And this is where I see alot of complaints from this device come in here. This scanner can do alot of things, clear codes, read emissions readiness and it's accurate it went against my 400 scanner and everything it read this thing registered. Except I noticed on this bad boy I can see when the last codes where erased on a vehicle so I can weed out those dealer cars that clear codes on their problem child cars as they enter the auction. Imo this device is a good value **UPDATE*** 5 Months later and this little devise is my best friend. It goes to auctions 4 auctions a week and probably scans at least 50 cars per auction. Its never been glitchy or wrong. Its also amazing on a carlot scanning a vehicle in front of a potential customer brings car selling to a whole new level they can see the vehicles readiness monitors. SO I have a 2nd one now just for the sale lot. I absolutely love this item and the quickness of scanning a vehicle. I can scan vehicle almost on the auction block if need be for those cars that just appear that you never saw parked in the sale lot.. Also for kicks i scanned a Maserati and it worked..Scans Mercedes c class to. I am pretty sure it will do a basic scan on any car with an OBDII port at this point
