Yes - and for a number of reasons, I would not recommend it.
It does not work with Hoffman type frames - I'm in the UK and most people use hoffman type frames - I think about 70% in all. When I found this out, I asked SHF to mention this on their site as it's an expensive item and useless if you have Hoffman type frames but, to date, I don't see this references so I'm posting a warning here.
It works reasonably well if your frame sides are completely straight and are parallel AND if the cappings are well proud of the frame sides. However, it needs two passes at right angles to each other (i.e. to create a 'cross' cut) to enable honey to flow. For this reason, I would recommend that supers with wide spaced castellations be used. It is difficult to puncture cappings that are not proud of the frame sides. I resorted to scrapping with a knife blade to puncture low patches of cappings.
However, I also agree with Robo - a lot less honey is extracted through the perforated cappings than those uncapped with a bread knife. - I haven't done a controlled test but observationally, a lot more honey 'sticks' in the frames after extraction compared with frames uncapped with a bread knive. About 75% of my super frames are hoffmans so I had to raid the kitchen for a knive to uncap them so the visual comparison was easy. I also found that I had to spin frames for much longewr than bread-knife uncapped frames to get any reasonable extraction.
Finally, and this will only be proven next year, but the uncapper fairly shreds the comb that extends beyond the frame sides. I suspect that when the bees try to repair this comb for re-use next season, it will result in very uneven cappings which will make the process next year less efficient.
Not recommended - a nice idea in theory and well designed and constructed but unfortunately, quite poor in execution. Also, v expensive!
