it is perfect! ordered 28.11., came 3.12. at first start I recommend to watch one of the videos on Youtube. At first, I connected it to my car battery charger and it wasn't work. There was e02 trouble code. The problem was, ghat charger gives 16V and recommended voltage iz 12,5V. When I connect it to the car battery directly it starts in no time. It heats super and fast. Will test it again and if there will be any troubles I will wrote aditional feedback. Just buy!
Shipment arrived quickly, goods intact as described. I have tested it and I am very pleased. The device is easy to use and fulfills its task. The only drawback is the lack of an exhaust muffler. A bit loud work. A big plus for the seller
