When I received this, it was bigger than I expected, but it has a good clean finish, and doesn't look cheap.
Right away I tried it on a can , and kept turning and turning, and nothing was happening. I had read some reviews before and some users have complained that it is too complicated or doesn't work, and I was getting worried that it is really a difficult tool to use.
I rarely read the instructions, but this time read the few lines, and followed them. The can still didn't open. I tried it on the other side of the can. After one full turn, I did feel a subtle change in resistance, and stopped. I used the clipper/gripper, and pulled with a little force the the lid came off very nicely and cleanly. I went back to the other side of the can, and pulled on it, and that came off perfectly as well. Since then, I have not had any issues, as I know how it feels.The problem I had, was really not from this tool, but the many years that I was conditioned with other can openers. With this one, once it goes around the rim 1 full turn, it is done. It was too smooth and too easy, so I thought it was not cutting at all, while it already cut the rim on the first turn. All it took was a pull with the clippers.
So you really have to reset how you use a can opener when trying this, and you don't need to fight it. It works very well, and since then I have many cans that I have cut on both sides, and use them (or hope to use them) as molds [for stacking food]. {My wife is not very happy with me collecting empty cans}
Amazing product!!! Just be gentle with it and it will do the job. Only pull with some force using the clippers.
