It's a bit like the northwave 950 boots and the Mountain Slope Point 951 boots.
As a user, I have never used iron rock so I can't say which is better. If it is legal and the product is better and cheaper, I think I will consider it.
As a product manager, copying the design is plagiarism and laziness, I think it's not good. But design also needs to develop and compete, we only choose the best results.
I think the most important thing about the product is telling me what it can solve and letting us know why the product is good and not deceiving us.
The false propaganda of iron rock products by Chinese channel dealers makes me sick.
