Despite not having very detailed user instructions this heater is quite easy to use. It arrived in the nick of time - outside temperatures were dropping below freezing but with the heater on, my greenhouse never dropped below 6 degrees. The fuel consumption was as good as claimed if not better. The only downside for me is that some cacti and succulents don't like the carbon-dioxide given off when burning paraffin, I had to take some indoors.
