So far so good. I'm interested in how this product performs over time after repeated washing and ironing. They state the product should last the rest of the shirt's life, but that remains to be seen. For this reason I give 4 stars. Great idea, I hope this is something that can hold the look over time. My tailor charges me eight dollars a shirt to have this piece attached. It's not that bad, it's worth it. I would also recommend purchasing a hard collar attachment product.
