I've used these a handful of times so far. I've tested them on furniture and my washing machine. It worked well for both. I was installing some cabinets in my laundry room and then I thought about using this for the cabinet leveling and they worked great! If you have a good imagination there are more uses for these than described. I love them so far. I cannot speak for long term use since I've only had them a few weeks. Well worth the price!
