Sadly, experienced the very same thing. company sent a replacement handle, though I explained that my husband said it was more likely gear related. He was right....and they wanted me to pay to ship it fully open with a long die stuck in it.
We tried everything to remove the die to lower the shipping costs. At first, we were worried about not being too harsh with it (so they could see what had gone wrong) but eventually, we spent days yanking on that thing.
I would think by now, they'd offer to replace through JoAnns since they're everywhere in the US to make this easier for customers. I was unwilling to pay to ship because there was no promise to fix/replace.
When we finally got it open, the tiny gears were completely stripped & not from misuse, I assure you-----dad worked in metal business for decades, looked at it and said the gears hadn't been heated properly, likely that the whole batch was bad.
I do hope you have better luck than I did.
