I use these, there are also slightly better Figma joints on ebay from time to time, the only problem I have with revoltech is they are quite stiff, and need to be applied very well for any good use. Unless someone can come up with a way to loosen them, not sure how when they are the type of joints that go click, click, click when you move them. Have done some trial, and error, they broke out of the leg I applied them to many times. Found it's best to leave the joint completely in tact, drill, then glue them in place. Ultimately, I personally found them to be a waist of money (just my opinion, by all means give them a try) for cutting up an old figure for it's joints is a better deal, and yields superior results.
