In the past, when the packaging had a strip to pull, it was more user-friendly. Now that you have to "twist" them, it's inconvenient, especially if you're in the shower with wet hands or in a hurry.

Basically, it would be perfect if they were easier to open, it takes about five minutes to open the cellophane in order to wear it.

Use for over twenty years. The only thing I would like to improve is a 1-2 points longer cord.
