Query: Could not get it to cut

I spent a considerable amount of time trying to get this to cut 22ga sheet metal. Finally gave up. I didn't return it because I persisted on trying to get it to work by attempting to fine tune the rollers, which were wobbly and did not achieve proper opposition to achieve a cut, and the 30 days had past. Totally worthless IMHO.
