OneTouch Can Opener Review

OneTouch Can Opener
Bottom Line

 The One Touch Can Opener is a small device powered by two AA batteries (not included). It's designed to cut round cans of any size, but not odd-shaped cans. To use it, you just place it on top of the can and press the start button, then wait about 25 seconds until it finishes revolving around the can. A built-in magnet lifts the lid off.

Users who have arthritis or other physical limitations particularly like the One Touch can opener because it's easy to use, but overall, reviews tend to cluster at one extreme or the other, partly depending on whether or not the reviewer received a defective unit. We found quite a few complaints on Amazon,com and about defective units that don't work at all, use batteries too fast or stop working early. Reviewers recommend buying a One Touch can opener from a retailer with a good return policy.

  • Good for users with limited hand mobility
  • Cut off lid has smooth edges
  • Leaves sharp edge on can itself
  • Can get stuck on can if battery runs out
  • May not work on all cans
  • Reports of defective units

Some reviewers find that the One Touch works well on any round can, no matter what the size, while others report success only with medium-sized cans. Even enthusiastic reviewers mention some caveats: Though the One Touch opener leaves a smooth edge on the lid, the edge of the can itself is very sharp and dangerous. Therefore, this can opener isn't recommended for use around children.

The main drawback, according to owners, is that there's no way to know for sure when the batteries need replacing. If the batteries die while the One Touch is cutting open a can, the device often gets stuck and it can be difficult to remove. One user says it could take as long as 10 minutes to pry it off.

Overall, the One Touch can opener seems to work well enough -- provided you get one that's not broken right off the bat. Because it doesn't require users to grip a handle, it's well liked by those with arthritis.

We found the most illuminating reviews on the websites of two TV stations: KDKA (Pittsburgh, Pa.) and at KFVS (Cape Girardeau, Mo.). KDKA explains why an apparently defective One Touch can opener needed resetting; when the instructions are followed carefully, it works fine. At KFVS, however, it's clear that one of the two units really is defective. Tests at two other TV stations are also helpful, as are owner-written reviews -- especially at -- where nearly 200 users review and rate the One Touch.

Does The One Touch Can Opener Really Work?, Kristine Sorensen and Yvonne Zanos, Nov. 13, 2006

This video clip shows three tests of the One Touch can opener. The first two are smooth and effortless, but the can opener fails to operate on the third test, even with fresh batteries. The reviewer explains that this is because it was removed from the second can before it stopped on its own. A reset button solves the problem. The review gives the One Touch a thumbs-up as a good buy as long as you use it as directed and only on regular round cans. One caveat is that although the cut lid has smooth edges, the can itself is incredibly sharp.

One Touch Can Opener - Does it Work, the Second Time?, Lauren Keith, Aug. 23, 2006

This review tests two One Touch can openers -- one that failed an Aug. 10 test by journalist Lauren Keith, and another that a local viewer praises. Sure enough, the latter works fine, earning an A; the other earns an F because it failed to start, even with new batteries. Both testers conclude that it's best to buy the One Touch from a local or internet retailer with a good return policy, rather than from the TV ad with its high shipping charges.

Tests here find that the One Touch can opener works well on a regular can, but it didn't cut all the way through on a larger can. Despite this, volunteer tester Eveline Halgren says she really likes the can opener, and she's impressed by the smooth edges left on the lid.

A whopping 45 percent of the reviewers give this device the lowest possible rating; yet nearly a third of the owners say works great (though not on all size cans). Some owners complain of short battery life, sharp can edges or weird performance, but the main complaint seems to be that if the battery runs out while the One Touch is opening a can, it's extremely difficult and tedious to get it off.
