The items pictured in the description are not what I received but a much lower quality tip made from a very soft material.
The tips shown are made from a hard material that lasts about a month, but the ones we got have a smaller diameter pad and only last about a week (or less)before the metal reinforcing disc falls out. Then you are scraping the bottom of the walker on the pavement. We now have to keep spare pads in each of our cars, just in case. We've decided not to return these since this size is difficult to find in our area. I guess it's a good thing I ordered several of these.
I have to say we have made many purchases through Amazon, not because of price, but because of availability.
This is the first time we have been disappointed with anything we've purchased.
