I had never tried this brand before I received the samples because they're not sold in stores near where I live. They're not a popular brand around here.
They work relatively similar to the other brand though.
These o.b. tampons are very comfortable to wear. They're not too large that they cause discomfort, but they're not too small to allow leakage.
I don't keep mine in for 8 hours like the box says you can. It seems unsanitary to me. I usually leave my in for 2 to 4 hours, depending on when I go to the bathroom next.
