Ordered one and liked it, so ordered 2 more. Then one of the soft shoulder mats came off of one as we used it. So not sure how effective they are now. Update: The owner saw my review, apologized and took the time to write a letter expressing concern, noting that superglue on pad should make it good as new again. However she also sent us 2 more! She was awesome and we will continue to promote product and her… thank you so much. We do love them going up 3 flights of steps we groceries makes it very easy.
