“As a fermentation beginner, I found these lids to be a total game changer—no more worrying about jars exploding or having to constantly burp them. The quality is excellent, and they really do what they promise. Highly recommend for anyone getting into fermenting.”

“I'm using these for my hot pepper sauce and I'm thrilled. They're super easy to clean, create a strong seal, and I love that I can color code my batches. The silicone is non-staining and holds up to acidic ferments. Way better than traditional lids.”

“These are my favorite fermentation lids because they vent perfectly—no leaking, no mess, and they fit wide mouth jars just right. I still use a weight, but these lids make the process so much easier and more reliable.”

"I'm a first-time brewer and this jug was absolutely perfect for small batches. The price was great, it's easy to clean, and the quality feels solid. The lid seals well, and pouring is simple. I love how stable and well-made it is—it's ideal for anyone starting out with home brewing."

"I bought this as a backup for various brewing experiments. For the cost, I’m very happy with what I received. It's a solid product at a good value, and while I do wish the gallon mark was a bit clearer, it does the job perfectly for my needs."

"I got this to help my fiancé start home brewing, and we're both impressed. The glass is thick and durable, the lid creates a tight seal with no leaks, and the overall quality is excellent. It's a bit heavy when full, but that's normal. We would definitely recommend this for anyone getting into home brewing."

"I've been using these for several years, and they're still holding up for my annual wine batches. Highly recommend for anyone starting home winemaking—plant some vines and give it a try!"

"After my old plastic airlocks broke, I picked up these replacements and am very pleased with the quality and value. They are a bit taller than my previous ones, but they function great. The only small issue is cleaning if the carboy is too full and foam gets into the airlock."

"Finding a stopper that fits my 23L glass fermenter was a challenge until I tried this one—it fits perfectly and creates a very secure seal. The flexible, hollow design means it works with a slight range of diameters, and I'm confident it will outperform the pricier caps I looked at."

"I’m very happy with these airlocks—they’re simple to clean, the plastic is sturdy yet lightweight, and they worked great for my homebrewing projects. I prefer this design over the old S-shaped ones. No worries about cracking even if one gets dropped!"

"I had a minor issue where one arrived cracked, but after reaching out to customer service, they sent me two replacements. The response was a bit slow, but I appreciated the extra effort and overall support."

"These airlocks were perfect for my homemade wine. They sealed my five-gallon bucket well and let gas escape effectively. I’ve used them multiple times, and they’re durable and fit perfectly for my needs."

"I wanted a better seal for my 25oz YETI Rambler Straw Mug, since the straw would leak around the hole. I took a chance on these gaskets and they fit tightly, even surviving the dishwasher. Now my mug is as spill-proof as a regular straw cup—just needed to add a small breathing hole!"

"For my project, I drilled a hole in a plastic canning jar lid, inserted the grommet, and slid in a straw. The result? Perfect fit and no leaks—these are incredibly sturdy and simple to use!"

"I was looking for a cheaper alternative to metal grommets for my jars and tried these silicone ones. They popped into my drilled holes easily and prevented any sharp edges from cutting me, though they do wiggle a bit because my lids are thin."

"I absolutely love this set! It's incredibly dependable for fermenting, and I can easily keep track of my batches thanks to the clear design. The solid quality and ease of use make it a staple in my kitchen for everything from sauerkraut to cider."

"This airlock fits perfectly on my Carlo Rossi wine bottles, which makes repurposing them for homebrewing so convenient. Works exactly as promised!"

"The airlock feels much sturdier than the thin ones I've tried before. The only downside was that one red cap arrived cracked and didn't snap on, but otherwise, I'm pleased with the build."

"I’ve been using these for fermenting vegetables and they work extremely well. I like making my own lids, and these airlocks seal up nicely. Just be careful when drilling the holes in plastic lids, but otherwise, everything fits and functions as it should."

"I used these with both 5-gallon and 2-gallon food grade buckets, and the grommets were a great match for the lid thickness. The airlocks set into the grommets without any trouble, and cleaning is simple. They seem solid and long-lasting—definitely a good buy for home fermenters."

"The kit was a pleasant surprise, especially since it included an extra set of rubber gaskets—something I really appreciate because they can be hard to find. The manufacturer clearly thought about customer needs, and these have held up well with repeated use."

"As someone new to fermenting, I found these lids incredibly easy to set up and the water lock works perfectly to keep out oxygen. Watching the gas activity was a fun bonus, and I would definitely purchase this set again."

"I’ve been using these lids and water locks for years, and they have truly held up. They’re perfect for beginners—no need to burp your ferments, as the system deals with everything automatically. I love that you can swap out the water lock for a silicone plug without changing lids—very thoughtfully designed."

"I bought these to kick off my new mead-making hobby. While the product does what it claims, I noticed that the lids are a bit tricky to screw on tightly and the rubber gaskets can rip easily with the sharp metal edges, so handle with care."

"I'm impressed by the excellent value these airlocks offer. They're simple to use and work perfectly for my fermentation projects."

"At first, I was skeptical about the plastic material, but it turned out to be durable and does the job well. The rubber seals can get damaged, so I recommend wetting them and the airlock for a tighter fit."

"These airlocks are top-notch for fermentation. Just a tip: ignore the instructions about the hole size—use a 1/2" drill bit for the best fit with the grommets. That way, you'll get a secure seal and avoid issues with the airlock popping out."

"I've always relied on three-piece airlocks, but decided to try this twin-bubble style for a change. I found it a bit easier to use since there are fewer parts to assemble—just fill it to the line and cap it. It's a nice, affordable option to have extras on hand. Cleaning is trickier compared to the three-piece airlocks since you can't take it apart, but for the price, it's worth it."

"For my home brewing mead, I use this airlock and it keeps out fruit flies and gnats perfectly. The hard plastic construction is sturdy and reliable, although cleaning can be a bit of a challenge, but that's common with this airlock design. It's inexpensive and works well, so I'd buy it again."

"These stoppers are ideal for home winemaking—they fit my 1-gallon demijohn, seal tightly, and are very easy to clean. Plus, I don't have to worry about them breaking like glass ones. Delivery was fast and the price reasonable. Very satisfied!"
