The reviews on this product seem to be a mixed bag, however I have been fortunate enough to have received a good quality unit. Have used at multiple events, sometimes the unit is on 4 days straight for 10+ hours at high temp and no issues. I fill the base of the unit with water and it heats up the pans quickly. Only issue I have is with the drain which has a poor seal and is slow. Easier to just let the unit cool and dump the water.
