FERRODAY 12PCS Swing Top Glass Bottle Caps Flip Top Bottle Cap Beer Bottle Airtight Lids with 12Pcs Replacement Silicone Gaskets, 18mm Leakproof Easy Swing Top Stopper Fits 8/17.5/26/35oz Beer Bottle

Yes, the caps are a bit tricky to get on, but here are a few tips: 1) I found the rings will fit the clear Bud Lite with Lime bottles perfectly. The labels also peel off the these bottles better. 2) I used a metal chip clip as a clap to hold the bolt, ring, and nut in place so I could finger tighten it. Ironically, the chip clips were also bought on Amazon— I highly recommend the chip clips! We use them all the time. 3) I then wrapped a rubber band around the bolt, ring, and nut, and reapplied the clip to help held the nut in place as I tightened the bolt with the screwdriver. This method made the process take about 1-2 minutes per bottle. The tops fit great.

Comes as described and works grate. Due to the small size of the included screws and nuts, assembly may be challenging. Bottles used were pre measured to ensure proper fit, prior to ordering.

As shown in the illustrations, "one size does NOT fit all." Measure the top of your bottles. Difficult to assemble? Perhaps the first one or two. After you sort it out, easy peasy! I did however, forego the "carrying rings." Kind of says, "Hi! I'm a dork!" Hahaha. Great product. Would give five stars if the company made a similar product for other size bottles. Will reorder!

The product fits perfectly create a nice seal on both Coca-Cola and Sam’s Adams bottles, although the fit on the Coca-Cola bottle is a little loose meaning there’s a little movement in the metal ring that connects to the bottle. And Samuel Adams bottle it closes a little too tight. I don’t see how this was a frequently returned item. I wanted to save money on the cost of pop top bottles and these definitely do that.

I was so hoping these were going to work but they did not. I recently started wine making and was trying to recycle some old wine bottles using these instead of corks. They were a pain in the behind to assemble and after assembly they did not give a tight seal on the bottle. I tightened the bolt and screw as tight as it would go, but it just wasn't tight enough to get a good hold on the bottle to make the seal tight. I bought them way to early (wine takes months before it is ready to bottle) so by the time I tried to use them it was to late to return. Bummer........

Love these, I bought them for the amber beer bottle collection I had. They are perfect. Had no trouble putting them on. I just wished I bought more…they seal perfectly. They are very sturdy yet easy to open and close. It’s a great value.

The biggest problem i found with some reviews for these caps was whether they fit used Sam Adams bottles or other homebrew bottles that are of the same size. I am very happy to say they fit perfectly. The Sam Adams bottles i had(old cherry wheat bottles) allowed me to connect these quite easily. The fit on these bottles seemed be a little bit snugger that on the other homebrew bottles i have. Both types of bottles seem to hold pressure quite well. I am working on a 2 month pressure test comparing these to counter pressure filled capped bottles of both types and the swing tops of both types. I will update this review when i know how they hold up. So far the week that beer was bottle in here showed no sign of carb loss over that time. If they continue to hold pressure i will be buying lots more. The ability to remove these from bottles and reattach to new bottles (i.e. if you drop a bottle and break it) will probably save lots of money over other flip top bottles if the will hold pressure. I would definitely recommend these to anyone that wants the convenience of flip tops without having to pay 30 dollars a 12 pack if they have old homebrew bottles already. Cheers and happy brewing! Edit Dec 2022: So I forgot to update this review. Happy to say I'm still using these alongside some grolsch bottles. I had these hold pressure easily for 6 months. Works great!

The item I got does not fit any of the bottles I have, in multiple sizes. The video makes it look easy to install these, but that metal neck band is VERY STIFF and needs pliers to squeeze it shut. Mine aren't circular, either, they have corners. The screw hole is barely big enough for the screw and you can't just push it through to the other hole, I had to screwdriver it through and yhen use pliers to get the band tight enough to get the screw to feed into the opposing hole. After a full 30 minutes of struggle to get one installed on just one bottle, I couldn't get the thing to close shut. I won't be able to use these at all.
