I bought these bushings because they are aluminum and I need something that will not rust. But they are not difficult. They fit the purpose I bought them for but I wouldn't use them for leather or other things that require tension like shower curtains etc. The rings are very thin and will most likely bend under pressure. But they are also easy to use as the grommets are easy to install.
