Wide Mouth Mason Jar Lids for Curing, Harvesting, Fermenting, Canning. Vacuum Sealed Patented Tech that Includes 4 Lids with Extraction Pump By Burp Lids

The quality and value of this product is grossly understated. Here is what I love:1. Reasonably affordable2. Idiot Proof3. Seals well most of the time4. Absolutely creates a vacuum inside the vessel5. Removes the oxygen and prevents the mold6. Degasses the contents - so if you put coke or beer in it, it is going to go flat, fyiHere's what I don't like"1. I don't have enough of them2. The plastic hand pump quality is not great. You may find you need to lube it occationally.Here's what is important to note:1. You have to be diligent and ensure any seal including this one. Once a week I go jar to jar (all of my product is in glass mason jars from pint to one gallon and take a couple draws with the pump. Most do not need it. But it is good practice to ensure your vacuum and seal. One time the seal just wasn't working. I tool the lid off, cleaned the seals, reapplied the lid and it was fine. Bottom line is if it fails, it is likely a maintenance issue on you, not the product.

Works awesome which i would've bought their electric pump though! But this,their lids,along with some amber Mason jars and some rh meters ..oh and a black bucket and lid lol and then your all set up for some curing lol

Burp Lids $19.99 (after a $10 off coupon): 4 lids and a hand pumpAIEVE Lids $14.99 : 6 lids(There is an AIEVE set of 6 lids plus a hand pump and a pounder for $21.99 but I didn’t want the hand pump or pounder.)So I wanted 12 fermentation lids.AIEVE was $29.98 for two packs of 6 lids (= 12 lids).Burp Lids was $59.97 (after $30 off in coupons) for three packs, each with 4 lids and 1 hand pump (= 12 lids and 3 hand pumps).I didn’t care about the hand pumps because I wanted to buy the Burp Lids Automatic Pump $24.99 (after a $5 off coupon). I read some reviews that mentioned the Automatic Pump worked with any brand of fermentation lids). The notches in both brands of lids helped me screw and unscrew the lids much better than regular smooth lids.Two packs of 6 lids from AIEVE and the Burp Lids Automatic Pump came in at $54.97!!! FIVE DOLLARS CHEAPER than three packs of Burp Lids (4 lids 1 hand pump per pack = 12 lids and 3 hand pumps).The packaging/branding of the Burp Lids is really nice. And the black and green colors make the lids look really sleek and shiny BUT apart from the colors, the lids were identical to the AIEVE lids.I took all the Burp Lids out of the packaging along with the pumps and examined them for imperfections since a lot of reviews mention receiving defective lids. All 12 lids were in perfect condition. I tested each one on a Ball brand jar, they all fit well. I also tested the hand pumps, they stink, they are very low quality pumps and not smooth to operate at all, all three pumps had the same problems. It takes at least 3 pulls to get all the air out of a jar. I can’t imagine fiddling with the hand pump through 12 lids. I also tested the Burp Lids Automatic Pump on each lid to make sure everything worked right, and I’m happy to report everything worked fine.Next I took all the AIEVE lids out of their packaging and examined them for imperfections and defects too. All 12 were in perfect working condition. I also tested each lid on a Ball brand jar, using the Burp Lids Automatic Pump with each one. They all worked perfectly.Regarding the Burp Lids Automatic Pump, you can just place it on the top of the jar, push the button, wait for it to turn green, turn it off and take it off of the lid and there is a satisfying pop sound when you take it off proving the seal. But I felt it worked better if I just held the Automatic Pump with a little bit of downward pressure against the lid, it made a better and stronger pop sound. Also you can feel it’s a stronger seal when you take the Pump off the lid.I tried to figure out which brand was better but they are exactly the same. The only difference I could find was the weight of the lids, Burp Lids lids came in at 39.2 grams and AIEVE lids came in at 41.1 grams, I don’t know that the weight difference makes any impact on the quality.If the Burp Lids were cheaper I’d be inclined to buy them, the bright green and shiny black, make them look very pretty and high end. But the price, even with the discount coupon, doesn’t make sense to me. The AIEVE lids aren’t quite as pretty or eye grabbing but they work just as well as the Burp Lids so I’m keeping the AIEVE lids and the Burp Lids Automatic Pump, they are a match made in heaven.I’m giving Burp Lids 4 stars due to the high price and sucky hand pump.I’m giving AIEVE lids 5 stars because they work great and are super affordable.I cannot emphasize enough that no matter which brand of fermentation lid you buy, you should buy the Burp Lids Automatic Pump, the hand pumps are completely worthless and a pain in the neck.See my Burp Lids Automatic Pump review for some videos and extra pics.

These work great but you should still check them regularly as they occasionally leak. But a great product!

These sounded like a good idea...but irl- not so much.They all leak. 1 of 4 had a major leak issue- you could pump air out and if u try to burp it 10 min later- u coodnt- it had already leaked air. No satisfying *psssst* noise.The other 3 mostly worked... i guess- but they arent air tight/smell proof by any means- i can smell my herbs from a few feet away while they are "sealed".Thats 100% a deal breaker for me.And overall, tbh- it really doesnt save any time or energy versus just taking a lid off the jar.Like, none at all... maybe if you have dozens of jars youll save like 5 min...If they work properly... and u dont mind smell leaks...Def returning.

Either won't seal or don't keep a seal, is what I've faced with these. These lids can be tricky to get on which can prevent a seal. The rubber burp which helps keep the vacuum tend to be too small or off centered. This allows for leakage. The others took a lot of tries and eventually sealed after some toggling and taking the lid on and off. Eventually all lids failed, but after several attempts I got a few to work properly. In the end, only 2 of mine never held a good sealUpdate: For best results with these lids.Make sure no debris are in the following places: rim of jar or outter sides of jar, lid's rim seal and lid's inner sides.Put the lid on top of your jar.Rotate counterclockwise until lid falls in place.Turn clockwise until tight and snugMake sure burp is centered and not cramp on any side. Do this before and after you use the pump to extract the air from within the jar.

Works great. I use it to store seeds for now and no issues .I use Ball 32oz wide mouth jars.

I went through a couple of the plastic pumps, one from a gift pack I received and another from a second pack I bought myself. Maybe the manual method isn't for me since the hand pumps kept breaking but I really like the lids ability to get out all of the gases and very quickly too. I have since been using the automatic mechanical pump on the lids which gets the job done just about as quickly and doesn't leave me worried about anything getting broken in the process :) The seller also refunded me when hearing of my troubles with the old hand pumps. Side by side, I'm liking the cure from the jars with these lids better than the ones I have with regular jars/lids, thumbs up overall.Edit: still smoking on jars from that cure, YEARS later. Quality may have even improved with time, not disappointed!
