I do not know if I came across a faulty series but after one use, I noted that it lacked a bit of material on sides, where the two sides of the grill are touching. One day while cooking some meat, the coating is peeled off when I tried to take the meat with a small shovel, wood is not supposed to scratch anything, why would the coating not stick to a panini? an undertaker? So I quickly returned the equipment, too dangerous, many things are not hazardous to health, except some but we learned 10 years later, I do not want to participate in the trial.
