Too soft
I bought these because my noise gets oily and I thought the grooves will help keep my glasses in position, but I don’t like the little holes at the bottom I thought there was a little air pocket for suction but they have little holes I worry about things getting in there like dust, Only if you wear the same pair for a while. My glasses have silicon on them already, i brought these because of the little grooves but it’s too soft so it doesn’t  work as good as my original silicon pair. My glasses still slid off. They are soft squishy easy to bend in any direction. There is some pros to it for example my noise doesn’t have marks, I don’t feel them resting on my noise bridge,
