This is a great little capper and has been faithful for about 8 or 9 batches. Eventually the magnet becomes dislodged and more of a nuisance than a help, also the caps are starting to become stuck in the metal busing, so it requires some force to remove the capper from the bottle after pressing the cap all the way down. The plastic holders for the metal bushing also deteriorate so I probably won't get many more batches from it. Generally it caps perfectly if you work slowly and rhythmically press down bit by bit until the capper sits flush on the bottle with both levers extended.
