I have used several times. Had to fix ine issue with gasket leaking. I was aware of the issue prior to purchase. Easy fix ... Just apply high temperature foam gasket in addition to existing gasket on both lid and ash collector. Cost less than 1000 peso. Unit control of temperature is very good, efficient use of charcoal. However charcoal in Philippines is not consistent in combustion temperature, so some experiments are needed to see what works for each type of cook. A supply of high quality charcoal would fix this.
