Awesome usb type c tool
I needed something to check the hardware side projects i create where I power then with type c decoys. This board helps me quickly diagnose and failures in design and is able to trigger output voltages for different type c spec level. The graph over time and stats feature is really useful and i am currently using this with the desktop app which is working flawlessly.

Good item but model delivered is other
The item advertised on Amazon India was the blue model with Bluetooth facility. But the shipped model was black without bluetooth. If the model available of only black then it should have been shown clearly and mentioned. All features shown and explained are for the bluetooth model but the item delivered is the black, wo bluetooth. My earlier review was rejected. I am sure Amazon will reject this as well.
