Easy and Effective
This is the second set of facial mask extenders I've ordered. The first were of a design that required too much fuss to apply and didn't stay in place. These are the exact opposite -- they attach easily, stay in place, are comfortable and keeps my facial masks snug. Best of all, thanks to these straps' provision of a stable and snug fit of these masks I no longer have a problem with my glasses fogging up. Great solution to what was a really annoying problem.
