Review on Vgate VR800 OBD2 Scanner - Advanced EOBD OBDII CAN Diagnostic Code Reader for Check Engine Light Troubleshooting by Travis Caminiti

Many years ago I got an OBD2 scanner without LCD screen. You attached it to your car, it took some measurements, then you had to hook it up to your computer to see what it read. It wasn't perfect. This system is much better. This device has a built in LCD monitor and you can interact with the system and get real-time readings from your vehicle's systems. If your car has warning error messages/lights, this is a great way to find out what they mean. You can also clear these warnings/errors. You can also pre-check the systems that will be tested when you bring your car for certification to make sure they are all good and working properly. You can measure your car's systems in real time and see how they change while the system is running. If you're having intermittent issues (e.g. just turning on the air conditioning compressor) this way you can see what your other systems are reacting to in real time. ), leading to more information about the meaning of this negative test result. The scanner can also be connected to a computer if you wish to download the results (via the included USB cable). You can also update the firmware through the USB port. Overall this is a good OBD2 scanner with a good interface at an attractive price. If you've always wanted an OBD2 scanner, this is a good option.
