I received this extraction tool and first impressions are that it is well made and the plastic case comes in handy for organized storage. But when I tried the bolt extractor, my big disappointment was that they weren't exactly the right size. Size 3/4 is too small for size 3/4 and size 11/16 is too big. So you have a kit that needs to be scaled up, but isn't made to industry standard sizes. I ended up buying a reputable branded puller that was a size 11/16 and it works great and is the right size. I compared them side by side and they are definitely not the same size. I end up going back to Amazon because I can't have a tool that isn't the size it was made for.
