This unit is amazing value for money, it uses a bit more fuel than I thought it should however that is a small inconvenience compared to how well it heats up an area. It also uses less power from the supply at lower settings (H1-3) which extends the amount of time it can be used from my 12v 100AH battery which I am was not expecting and am very happy with. I found that the H2 setting (out of H1-6) was a great compromise for the amount of heat it produced compared to the amount of power it was consuming (around 1.2A).
Be mindful that the exhaust piping is about 3 ft long and can get very hot on full power (270c), I ordered 6ft extension which came in two pieces which gives me the flexibility to place it where I need it - bonus that the exhaust gasses have cooled a fair bit by the time they reach the and of the extended pipe :)
The only thing that could be improved would be the brightness of the LCD screen, other than that, I am super happy with this unit.
