Q: I DO like these 'lids'. The design is ingenious. Kudos to the inventor/developer. PROS Fits the tab perfectly Aids in lifting tab Convenient 'always on' Will reduce spillage CONS Will not contain carbonation Will not contain spillage Does not inspire confidence in opening can Possible injury to thumb when opening can All that said, some context is in order. Initially, I was looking for something to contain the carbonation for cans left in the fridge overnight, and reduce some slight uneasiness about nearby science projects easing death into my soft drinks. These looked very simple, and though pricey at eight USD, I appreciated the clever design. Ordered even though I realized these were not intended for my use case. The work very well for their intended use, and fairly well for mine, as noted above. There is only one caveat, for which I deducted one star. (I usually don't give the fifth star until I observe a high level of durability over time. That was not this case though.) The width of the two 'tines' that encircle the tab actually *impeded* opening the can. They press on the surface of the can that doesn't open. You're instructed to press on the tab with your thumb while pulling up on the back of the Barricade. On two cans my thumb went into the opening somewhat. There were no cuts, but I can see that as a possibility, unless maybe you have wide meaty digits. Using the device to try to open the can gave me the impression it could snap at any second. I found it much easier to open the tab as I always do, then attach the Barricade afterwards. For anybody who has trouble lifting the tab, using the Barricade to lift the tab up enough to grab it without the device might be a better way to go. Aside from the price, I'd recommend these for their intended purpose. I'll get full caps for overnight storage in the fridge, but I really like these guys for daily use. They work well enough for me and possibly better for others.
