Hab unpacked the good piece and was curious about the use. Tested on the same evening. Handle apart horizontally attached to the can handle together again and go. Can rotate pleasingly light. In the end I thought at first it would not have worked. But on the contrary. The lid was perfectly separated from the can and both have no sharp knew. Since I was more than pleasantly surprised. That part I can wholeheartedly recommend it! Man requires little power and there is no danger to the usual cut on the lid.
