I've been using a Kamado-san for many years. I bought this one last April for an overseas business trip, and after using it a few times, it short-circuited, leaving only the inner pot (＞人＜;) There's a small crack on the surface of the inner pot‼︎ It looks like it's just on the painted surface, so I don't think it will affect use. I've already sealed it, and to prevent the rice from absorbing into the pot, I've never washed it with detergent. I want to sell it quickly, so I'm looking forward to your comments ✿
