AUTOPOWERZ Elm327 Bluetooth OBD II Universal Vehicle Diagnostic Tool Item Name (aka Title) Big Black

I bought this as I was interested in tinkering with my car. It works fine with my Maruti Suzuki Wagon R LXI (2011 Model), I Tested it with "Car Scanner", "CarBit" & "Torque (Lite)" apps on Android 9.0. I am now able to see a lot of additional information (Detailed Speed Reading, Engine Load, Engine RPM, Fuel Economy, Voltages, Coolant Temperature etc.) not shown on my car dashboard.The only complaint I have is that, I have to delete the bluetooth connection from my phone's bluetooth menu & re-pair the device every time it is plugged/unplugged as for some reason my phone doesn't re-connect to it if it is already paired & disconnected. But this is a small annoyance.There are a lot of bad reviews posted here & after reading them, I came to the conclusion that most of these people are probably not using the device correctly or their car make/model is not compliant with OBD2 (apart from those who got a faulty module). These negetive reviews could have been avoided if the seller just sold these modules with an instruction manual (Even an instructional website would do). This is a diagnostic tool & although it is kinda "plug&play", you need some know-how to properly use the product. So read up a little before buying this.Verdict : Buy this If you are into tinkering with your car or want additional Information not shown on your car dashboard. I would not recommend using this in a professional capacity.NOTE : Information read & shown in apps will depend on your car make & model.NOTE :The module is quite big in size, so I would recommend buying an OBD2 Extension Cable with this if your car's OBD2 Port is in a place where the module would hit your legs while driving. I bought one & relocated the module to a more convenient location.

Good

Not able to connect with my mobile phone. Company should provide user manual so that customer can connect easily. Product is good but I don't know how to connect it.

The last time I cleared some error code the local mechanic charged 500 rupees. Now I can clear codes as many times as I want for a little money. Works well with torque lite on my ford figo

Not suitable for Renault

There is error lamp lit when i check with the tool there is no error. Unable to reset
