Review (3/5): You get what you pay for
I thought getting the cheaper ones would be fine. And they are FINE I mean they work... but it's clear they're cheap. Every single one has scraps from when they were punched out during manufacturing. The edges are almost sharp, and the little flakes have gotten in my eyes. I have to pick them off before I use the pads. Just not ideal but not something I feel comfortable just throwing away.
