We are relatively novice bee keepers (two years). This extractor worked exactly as it was supposed to with minimal effort on our part. As you would expect, since this is basically a pretty good size centrifuge, it must be bolted down or it will "walk" and become very unsteady. Initially, we mounted it on a single board about three feet square. That did not work. We then mounted it to 2x6s about five feet long in a V shape and stood on the ends of the boards. This worked perfectly. It took about 10 minutes to extract the honey from the two frames after the cells were opened.
