The quality of this godiag gt100 tool is quite good for the price. It comes well packaged and with all you need to connect this to a car and diagnostic tools. One of advantage to have this in the garage would be a possibility to connect multiple modules at once to this junction box, which would make a job for mechanic much easier and eventually faster than searching for faults. Overall, it is a good tool to have in the professional garage if working with a car's electrics and faults, which eventually would save time.

I have multiple brands of Breakout boxes and this is the easier one to use wit additional features for doing ecm, ecu repair on vehicles.
Great product for doing diagnostics, vehicle immobilizer & security work whether it be on the bench with the included power adapter or in the vehicle with the OBD II port supplying power.
With expensive scan tools these days I always use this to verify that the networks are communicating properly and that there is proper power and grounds being supplied to the box assembly. You don’t want to hook your very expensive scan tool up and it be fried because you didn’t have the proper powers and grounds from somebody’s previous shoddy work on a vehicle.

Please make sure you’re fully aware of the capabilities Nd use of this product as with little or no experience just as with other tools, equipment you can do thousand of dollars to a vehicle if not properly trained or knowledgeable with what you’re doing.

I've used Godiag GT100 on a Mercedes and the VVDI2 platform. If you know what you are doing it’s a great tool which shows the results in real time.

Plugged the socket under the dash into Godiag GT100 and turned the ignition. Soon after, a few of the LEDs lit as we expected with varying levels of brightness. The brightness of the LED also requires interpretation, as a weakly lit LED lets us know how good or bad the particular part of the car is.

My partner is quite into cars and always like to perform health check for our cars. He has been playing with a few from other brands but not as sophisticated as this one. Although it looks complicated due to it's size and no. of ports and no instruction leaflet, but men always got the talent to figure out how to get them connect and google to solve the issue. His comment after using it is very good, give early stage of signal/alert that need to work on before it completely breakdown, this helps to save a fortune and avoid a great chance of standing in the middle of nowhere waiting for rescue. And one other best thing he mentioned is this box supply the vehicle with power when you are transferring batteries to avoid data loss which is another plus to this box.

Can be connected with multiple modules. Strong compatibility, making use and diagnostics more integrated and robust.

The package came well packaged with various leads to be used for operations but the only thibg I don't like is that there is no instructions to guide on using it however its meant for those that really know more about technical operations of a car. This is an excellent device for mechanical work and I can assure you that it is not a waste of money.

Using a Vident scanner and the Godiag GT100 breakout box to perform a bench test for the ECU remove from the car (with can-bus error, airbag light on and niggling power problems, but no idea get any further). Turned out to be a corroded pin that was preventing the communication. Great outcome and saved a fortune. Fantastic bit of kit and you don’t need an expensive scanner to pair with it.

GT100 is a great break out box.Will surely buy again.

Overall I'm happy. Build quality is ok. Easy to use. Just can't fit it all back in the box

Awesome quality scanner and device to figure out why you have a check engine light on!!! Great quality. Very Easy to use!! My husband is not great with doing anything with cars. Having this definately helps us narrow down the issue. Awesome price and value. Very pleased overall!!

Love this GODIAG GT100 OBD II Break Out Box. Great for ease of communication diagnostics.

Received in very good condition. every thing as per description.

I think it's the best ECU Connector in this range of price. Works very well in English, hope it improves in future. Fast delivery, good seller.
