It's a shame, this was the right overall design, lightweight, comfortable in hand, speedily performed it's task. It did not hold on to the can tops with its magnet that well.
The big negative here is safety and guaranteed injury to the hands/fingers by elder folks, children even the kitchen pros could forget to hold this safely and come up with severe injury.
Though the promo says it is safe to use, it is not. What happens is the unit using it's own cutting tool, by design, cuts lower from the can lid lip and into the can itself. Thus a person ends up with two very sharp edges, 1-underside of the lid and 1-the container part of the can.
I bloodied myself 3times and decided to buy another from Walmart and return this to C/S. I cannot get a refund because I cannot find the order but that's okay with me, it needs to be pulled from display before an unsuspecting child does real damage to themselves.
