Query: Total Failure

My 85 year old mother saw this on TV and thought it would make the chore of opening cans easier for her. I order one for her and it arrived in just a couple days. We installed fresh batteries and tried it on a regular can of fruit. It only made it about 2/3 of the way around the can and stopped. We followed the included instructions and used the reset button multiple times and tried the other procedure listed in the instructions for removing an opener with dead batteries. We tried for nearly 30 minutes to remove the opener with no success. Frustrated, I packed it up, still stuck on the can, and returned it.
