The shape & size of these pads are the reason for the four stars, instead of one or two. The adhesive isn't very strong, but the pads are so wide & long that it's difficult for them to move anyway. Though they are labeled as thin, they were still a bit thinner than expected. They worked fine for me, but I don't need a high absorbency level & I only wear pads at night or around the house. I probably wouldn't recommend these when leaving the house, I don't know if I trust them to absorb everything & not leak. I would get another brand if the prices are close, but I got these on sale & everything else was regular price, so I think they were worth the price.
