The overall impression of the product is pretty good. The diesel heater works well with no issues - so the product works.
The build quality of the frame is a bit flimsy but it does the job.
But there are few things you should know before buying this:
1. In my heater the remote control did not work, it just would not pair with the control unit.
2. There is no proper fuel filter installed, so you should buy and install inline filter (1-2€ or so, no big deal).
3. The fuel line after the fuel pump is soft, so I had to replace it with a hard nylon line, works better with the unit (2€).
4. The exhaust pipe gets super hot - keep in mind this. I wrapped mine with heat shield wrap (5€ or so).
Over all I am happy that I invested to this unit.
