I pre-ordered my Joule, Chef Steps let me know when it shipped, and I recieved it in excellent condition. Unfortunately the clip broke loose from the body.When I let the company know what happened they sent me a brand new one, would not let me send the old one back. Now I have two Joules, the magnet on the damaged one works in my cast iron Dutch oven. Both function as advertised, now I can prepare a vegetable at higher temperature and a protein at a lower one. I have come to enjoy new recipes cooked in a very controlled manner.
