This is my 3rd order... maybe my 4th
My overall rating would be 4.8. I first bought these in a quest to make wearing a mask all day comfortable while working  and they hit the mark... This is definitely at least my 4th order because I brought an order or two to give away to my office mates to share the wealth. The overall grade is less than 5 because I have had some break but vs the comfort and price of replacement it is still very much worth the buy.
Rating: 4 stars
