I believe the N235 is a great face mask. It fits good, and it is easy on my ears (especially combined with the ear saver strap, which keeps the mask from sliding up towards my eyes). Eyeglass fogging was less an issue than with other brand face masks I have tried. When I first ordered the face masks last November, there was an issue with no delivery after many weeks, and Germless did not respond to my email inquiries; so I cancelled my order. But after hearing they had been overwhelmed with orders and could not keep up; and learning that they had corrected their problems, I gave them another chance. First, I emailed them to see if they would respond...they did within an hour. So I ordered a mask, which I received within two days of my order. Since then, I have ordered additional styles of masks, and they too were received within two days.
