I made 8 of them to replace all the bearings on an in-line skate just for fun. I knew they wouldn’t last long but wanted to find out how long they would last. About 2 minutes :). For very light duty use they seem to work well... they obviously won’t spin freely enough to compete with regular bearings but are pretty neat.
