I've ordered these a couple of times for me and my family. Here's my experience
- Noseclip significantly prevents fogging of glasses
- Back of ears don't pain, and glasses don't come off while removing the mask because it ties behind the head
- Pull tab is helpful
- Quality is very good
A couple of things to note though
- I didn't take measurements and ordered a medium according to weight guidelines. Turned out a bit too small for me (adult male about 70kg).
- If you have long hair tied in a bun etc, they can get stuck in the velcro. They untangle easily when you remove the mask, but still a small annoyance.
