Question: Does the sealer fit 12 oz. cans also?
Document: A bit of a gamble as it works great on some cans but not at all on others.Sorry for the tiny sample but it's all I have at the moment.works: Rockstar 16 oz, Monster Energy Import 550 ml, 21st Amendment Brewery Hell of High Watermelon 12 ozdoesn't work: Coors Light 12 ozWe also had Hansen's or Coke at one point and it fit one or both just fine.Good news for me is that my use is the Rockstars so no disappointment here.
Love this. Works as indictated. Fits 12 & 16 oz beverage cans. It's a new and improved model. Easy on and off.
Still, decent product for decent price. Although I ordered replacements, I also ordered a couple Beverage Can Resealers.Great product! (Note: "Stop-Top 3" is the model; each package contains 1 resealer. )So far, tried Beverage Can Resealers on a 1/2-empty 12 oz. Coke Zero can and a completely empty 16 oz. Monster Energy can. Both were airtight and spill-resistant.
My wife doesn't always want to drink a whole 12 oz. can of soda at once. The six ounce cans cost more than the 12 ounce cans. She reports that this device is effective at holding the bubbles for one day for one reopening.
This can top sealer works great! The very low profile will let the can fit between the refrigerator shelves where other caps won't. And it's simple to use and the seal keeps in the carbonation for several days, even when the can is less than half filled. It beats the Jokari Fizz Keeper which I also bought hands down. Will be ordering a couple more.
I read reviews saying it was hard to put on and that it doesn't fit. They're wrong. It works great and is easy to clean. It also fits my Rockstar, Pepsi, and Coke cans just fine.
It is definitely a high quality sealer. One of the previous reviewers said it doesn't fit on Coke cans, but it fits for me...not sure why it didn't work for him/her. Tight seal -- I put it on the Coke, than dumped it in a bag and carried it around. The can went every which way, but not a single drop leaked out. Now that's a tight seal.You will never get 100% fizz preservation.
Works perfect and fit every can I've tried it on. My girlfriend can never finish a can of soda, so she puts one of these on when she's done and it stays carbonated in the fridge for a few days. I also use these when out on the boat. I put lids on beer and soda cans, so if they tip over they don't make a mess in the boat.
I use it on the big cans of Rockstar energy drink. Usually takes me 2 or 3 days to finish one so I like to keep the carbonation in while it's in the fridge. Also helps keep the smell of the drink from filling the fridge. Seems to work pretty well.Only complaint, it is a little hard to get on the can. I don't have that problem with normal pop cans, like Mountain Dew. The Rockstar cans must be slightly bigger but it does fit.
I never drink a whole soda and am forever wasting them or putting them in the fridge half drank. The beverage can re-sealer works great. My sodas still taste good the next day, they even make the the cachhh noise when you take the re-sealer off. It is also really nice to have a lid on my cans in the fridge to prevent spills.If you're like me and can't or don't drink a whole can of soda all in one sitting I highly recommend this.
Answer: I have several of these.  I ONLY use them on 12 ounce cans.
