You hand crank the frames through two cutter heads and all cells are opened up. Almost all of the cappings stay on the frame making it easier for the bees when you put them back on to repair the comb. This means more honey for you. Uncapper now comes with instructional DVD.
We purchased this uncapper three years ago and really like it. We have 28 hives. While unevenly capped frames might need some extra scraping, we can easily decap 20+ frames in the same time as it takes for our 20 frame radial extractor to do its work, so things go quite smoothly. It is easy to clean, and we had no problem adjusting it so it works well and decaps both sides of the frame at once. Since it uses no heat, we can strain out the wax and have high quality honey from the uncappings. Actually, we get alot less wax then we used to when we used a hot knife, most of the wax stays with the comb on the frame, and not in the uncappings tub underneath the uncapper.
