Neat little tool and easy to use. It will run a diagnostic test on your vehicle and show the different codes that need attention. The thing I like mostly is you can sync this tool to your phone by downloading a free app and the app will suggest the parts you will need to fix your vehicle! Pretty neat tool at a good price.

This thing is absolutely amazing no matter the vehicle no matter the problem i was surprised when the blcktec 420 scanned a German vehicle and told me everything wrong with the car everything help from live data help me pinpoint exactly what the problem was it was never any guessing with this scanner and also has a app that connects to a wider data base find parts give u prices from different vendors all kinds of stuff trust me when I say this scanner is amazing does things the expensive scanners do that's why I was so shocked thinking about getting the upgraded one the have the screens a lil bigger but in my opinion this thing is well worth it if not more

This is a nice little device that does all the functions that most of the lower end units do (and let's be honest the lower end units are all pretty much the same except for the shape of the device and the box it comes in) Plus the added functionality of Bluetooth to send data to a phone app. That's much more rare and usually reserved for more expensive units. So, If you've ever wanted to have a Bluetooth reader and a handheld unit together for a better than fair price, this is what you want. The phone app is definitely better than most, but not the best (but considering the price better than what we should get for the $$$), and absolutely usable and I can't complain about it. As for the actual unit, the cable is way too short, display too small and it's nowhere near as large as the photos make it appear (See pic. Laptop mouse used to represent true size). Do I wish it was bigger with a longer cable? Absolutely. Would I buy it again? Absolutely. I'll give it a strong BUY recommendation.

It’s cool with this tool for the price it gives you the basic and advanced readings if you are mechanically inclined, and you still always work on old vehicles and now converting to the more modern this would at least get you started on how to diagnostic the newer vehicle. This tool is handy. It’s cheap. It works well.

I am not mechanic minded when it comes to engines, but I love that I can check myself, and go into a repair with some knowledge of what is going on. this one is worth having in your car care kit. Super easy to use the app gives tons of info and even gets you quotes for the work you need .
