I got a set of these (they are sold, and should only be used, in pairs) and have used them to change wheels. What can I say? They work. And they are very well done, high quality. They are about twice as expensive as your common jack stands that you might buy at Walmart but are worth the price. Walmart stands won't work on BMWs and you can still pay more elsewhere for stands that are not as nice. Recommended.
