So far, so good. I'm interested to see how this product holds up over time, after being washed and ironed multiple times. They state that the product is supposed to last the duration of the shirt, but that remains to be seen. For that reason I give it 4 stars.

Great idea, hopefully this is something that can sustain the look over time. My tailor charges me eight bucks per shirt to install this product. Not too bad, it's totally worth it.

I would also recommend purchasing the stiff collar stay product as well.
