Review (4/5): I like these the best of the different extenders I've tried
I was getting tired of mask bands making my ears stick out and dig into my ears, so I decided to try mask extenders. I tried three different kinds, all of which allow you to use different slots or nubs to adjust the effective length of the extender.
Of the three extenders I tried, I thought this “wing” type would be my least favorite, but it turned out to be my #1. It’s not pretty, but it works the best, when compared to the types that have you put the elastic around round nubs and to the manually adjustable extender I tried.
I prefer to wear the extender high up on the back of my head. This seems to be the best position for me to keep my mask in place and against my face all around. Because this extender is silicone, it doesn’t just slide down. There’s enough “stickiness” that it stays put. (I don’t mean it’s literally sticky, though.) The wings are big enough that once you loop your elastic around your choice of wing, it stays put. I can pop my mask on and off easily, and nearly all the time the elastic stays attached to the wings I’ve picked.
