As Richard says, very good but use the right fuel as much as possible. It's a bit disingenuous of Coleman to call them multi-fuel, I think a multi-fuel burner should at least burn fuels as heavy as paraffin, as light as petrol and anything between. I have both Coleman stoves and lamps, they all work fine but their construction is a little on the lightweight side compared with, say, Optimus or Primus. The possibility of noxious fumes from using road fuel hasn't been mentioned yet in this thread, so I'll just mention it. Use outdoors ONLY if you use road fuels. Several other threads have covered these issues.
