I took the class from Jean Brown at the Road to California Quilt Show last January on how to use the Aunt Becky tool.. She is a very nice lady and very patient at explaining how to use it. She is very fast with it, but used to using it, of course. It takes just a bit of practice, but does make it easier to make even stitches without sticking your fingers with a needle. I bought 3 of them from her so if I lost one I would have a back up. I haven't used it much yet, but I do really like it.
