Have bought the grill for camper vans. The first attempt was a little disappointing: Only little heat and then only in the middle of the grill. The next night, then the second attempt: the wire basket really fill with as much coal as goes in, fill the fire bowl with burning gel GOOD, turn on the fan and light. After 2-3 minutes man can grill. The grill is really really hot, toward the edge a little cooler, but this is almost like a two-zone grill. As it started to rain, we have borne the grill during operation eifach in the camper and further grilled. Laying After dinner just to "fire basket" with the help of tongs out nd let cool. Conclusion: I'm excited !!!!! The grill is ready for use within a very short time, has enough fire for about an hour and then after the "removal" within 20 minutes cold again. The only downer: The fan noise a bit annoying, but the benefits can be quickly overlook this flaw. By the way, I use ordinary charcoal and a burning gel by the Bauhaus - the original Lotus products you need here is definitely not!
