This mask fits perfectly. The nose clip gives a good snug feel and it’s big enough to cover the entire face all the way down to your chin. Also has the white filter! A+++
I have used these for years and have found it to be the best, especially the convenience of loading it with one hand.
I can't use expired test strips, I need the current year. Also, I never received the free contour meter. That was false advertising!!! I'm dissatisfied!!!
I have only opened one box but they are working fine so far. I did not receive a Free meter. I only bought test strips.
