Query: replacing the lid is nice, but it does not always work

The ability to replace the lid is nice, and so is no sharp edges thing if you are clumsy or have kids, but I regretfully found out it does not open all cans. Out of maybe 5 or 6 I tried, it could not handle one. What good is it if you have to get another can opener?Even when it does open cans, it is not the most user-friendly can opener I've had (and I've only had two cheap ones ever before, haha). It sometimes slips and you have to re-place it and continue, which is annoying and tricky because the spot where you stopped is not easily visible.In short, you have to value the advantages pretty highly in order to overcome the disadvantages.
