2.1 / 5.021 ReviewsNot an upgradei have five big mouth bubblers, and was excited to get these when they came out. Unfortunately, they were quite the disappointment as they would not stay in the opening (kept sliding up). I would not recommend this product.February 4, 2016Response from Midwest SuppliesHi Kyle,
Thanks for filling out the review. I'm sorry that the universal lids are giving you trouble. One thing to keep in mind is that they will seal much better if the mouth of the bubbler is dry when the lids are inserted. If you'd like to contact us though, we'd be happy to work on a resolution for you.November 2, 2016Midwest SuppliesThird try and it still isn't rightI think this is the third lid they have made for the Big Mouth Bubbler and again, its a failure in my opinion. I just bought the Universal lid listed here and have the screw on lid before this one. Both of them have been problematic. This one is very flimsy plastic with some nice silicone to attempt at creating a seal. You have to push down on it to try and get it seated and then it shifts back out slightly when you let go. If your airlock is on already, expect a lot of bubbles to go out as you push down and then a significant amount of vacuum and sucking airlock liquid back down into your wort since the lid will not stay in place after pushing it down. It is VERY frustrating and another cheap/poor design. I absolutely love the concept of the big mouth carboy and would gladly pay 2-3 times the price of a high quality lid that works. Instead they seem to crank out different lids like they are disposables. Perhaps they just want you to buy one lousy lid after another in hopes that one will finally work.March 22, 2016Response from Midwest SuppliesThanks for sending the review - sorry to hear the lid is not working great for you. Some have played around with editing the screw down lid to go around the new lid to hold it in place if yours wants to pop up. Inserting dry can also avoid any movement like that. We'll keep looking into solutions for the perfect lid. Let me know how I can help you! Cheers! James J.November 2, 2016Todd JStaffSolved the issue!This solved my issue with trying to seal the big mouth fermentors! If you have issues with them popping off under mass pressure, you can trim the new lid and allow for use with the original plastic screw top. Again - this was a huge improvement over the original top!!August 16, 2016Big disappointmentLike several others I have read here, this lid is an extreme disappointment. Impossible to get a good seal. Why not come up with a solution that works with the original screw top. Like the bottle, hate the lid. Wont be buying anymore.November 13, 2016Great Vessel...Terrible SealI was so excited to see a carboy I could easily clean. The problem is the lid does not stay in place. I have to use a ratchet strap to keep it closed. Any liquid on the o-ring and it pops off. I ordered 2 of these, the first one has the screw on lid which was also terrible. The seal provided was too thin and you had to tighten it too much to get a good seal. I ended up having to order the new style lid and cut a hole in the screw on lid and use that to seal it off...works great...the problem is they no longer make or stock the old screw on lid so I'm stuck with the new style and having to tie it down...very annoying. DO NOT BUY UNTIL THEY IMPROVE THE LID!February 16, 2017GARBAGE!I bought 5 of these thinking I could replace my classic lids, I also did it simply because you can no longer purchase extra screw on tops for the glass bubblers or the two piece for plastic ones (I've got roughly 5 carboys of each). Basically, it was this or bust.
These things keep slipping up. I saw the comment about 'they work best when dry' which is as insane as expecting my 10 gallons I just brewed last week using these for the first time to have not gotten infected (thanks for THAT $100 down the drain btw NB). The whole reason the caps are wet? StarSan.
I suppose I could purchase cinder bricks to weigh it down until things dry, but thats asking for things to break or spill - especially the glass bubblers. Shouldn't a product designed for homebrewers...you know...work with home brewing methods? Unless there's some dry powdered sanitizer I'm unaware of, these products are useless.
I'm shopping ebay to see if the old two piece lids are available so I can TRY to replace these, but if I strike out I'm returning all the bubblers I just bought too. this is ridiculous :/March 21, 2017Purchased

We are sorry that you are disappointed with the lid, but will contact you to see if we can find a way to help with a better experience. One note on Star San, according to the general use instructions, all homebrewing applications should be allowed to air dry before use. We will contact you soon with some tips, tricks, and support to help improve your Big Mouth Bubbler experience.March 21, 2017Todd JStaffThese lids are the worst, never ever buyThese things don't work. I don't know why they ever thought of making these. Read all the reviews on here, on other websites, they do not work. Under good fermentation they pop up, losing the seal. I have tried several of them, I have tried making sure everything is dry before placing in... nothing works other than weighing it down with a weight of some sort. Horrible. Wish I never bought the big mouth bubbler because of this horrible lid.February 21, 2017Works great with Little Big Mouth BubblerFits perfectly with the Little Big Mouth Bubbler and seals very well. There were several times where I had trouble getting the original lid with its foam gasket to seal completely but it was easy with this lid.March 7, 2017Purchased
