Query: It's a sticky one

I bought two and I tried them many times but I failed. The first trial was done by inserting the dough in it as normal. After I got it out from the oven, it was sticked strongly and I pulled it out but it was destroyed. The second trail I used some oil and flour but I failed for the second time. Also, the shape of the final product wasn't good. I stopped using them and I returned back to the manual work to produce the professional baguettes. I don't recommend it.
