Extends life of shirt
Instead of donating this shirt to charity, I get to keep it although my neck size has increased.

Very useful!
These were just what my husband needed and cheap enough to replace when they get lost in the wash.

Not as big as you might expect
The product works well but just doesn't stretch as much as I expected, however loop 2 together and it works very well.

Disappointed.
The extenders are wry difficult to fit into the shirt button holes and are essentially useless.
