It serves the basic purpose for what it is designed..i.e. extend the collar size. I can wear tie again.

Great extenders works great

Seems to work well. Product as described, fast Amazon shipping.

Whoever came up with this invention is amazing! I have the toughest time finding dress shirts because my fit is 14.5, 32/33 Slim Fit. The chest and sleeves fit awesome in that size but the neck is tight. But if I go up a size on the collar it screws up the chest fit! So for weeks since I started wearing these slim shirts they were like choke holds when I'd wear a tie. I kept thinking there must be a way to help this. Then I found this product. Easy to put on, extends the collar, feels great, and you don't see it when I put the tie on! Excellent purchase, so pleased!

Extended collar to take a tie.

These do give an extension when your collar is too tight, but a different material would be more comfortable. Also the button is more like a rivet and pokes your neck a little. There were no instructions included in the package.
