I ordered the KIWI 3, took it out of the box and inserted it into my OBD plug. It connected fine and I drove around a few minutes to test it out. Turned off my app and left it plugged in. 30 minutes later I tried to reconnect my app and it would not connect. I went to unplug it from my car and it was really hot and no lights were on. The next day I tried to plug it into a different car and I got no lights. I shipped it back got an RMA and asked them to cover my shipping costs to get the clearly defective device back to them (I Know it s only $7.15) but why should I have to pay extra for their defect? I already paid once for shipping. PLX please do the right thing RMA# 111706.
