Gamma2 3.5-7 gal. Seal Food-Safe Bucket Lid, White

Great idea, terrible manufacturing. These lids are not even remotely airtight or watertight. I spent at least 10 minutes with a pocket knife cleaning up all the excess plastic that seeped through the mold so that the o-rings would have flat surfaces to seal against. I even removed the o-rings and cleaned up the grooves they sit in. I then held the bucket while my son used his entire weight and strength to tighten it. There are still significant leaks if I put a little water inside and turn it upside down. Plus, as others have noted it is very difficult to get these onto a bucket. I weigh 170 lbs and had to jump on the bucket to force the lid on. My body weight just standing on it was not enough. I had to jump/stomp on one section at a time. Ridiculous. And it looks to be impossible to remove them in one piece without ripping out your fingernails to the lip on the bucket if/when the ring finally lets go. Utterly useless for long term food preservation. I also did not appreciate the gooey sticker on the inside. I would prefer to have the adhesive mess outside my food, thanks. Not that I will be using these for food anyway at this point. Maybe if you are strong enough to install them the first time and you don't require an actual seal they would be okay for something. But there are cheaper lids that don't pretend to be airtight, so you might as well use them instead. I wish Cary or someone would make some that actually work because the idea itself is great. But the idea itself doesn't keep anyone's food dry.

We've had ours for almost 3years now and they're still keeping food sealed for us!

I had a bunch of food stored when a tornado hit. I used these lids and the plain snap on lids. Everyone bucket with these lids got water inside and ruined the contents!!! The cheap lids kept the contents dry!!!! Do not waste your money on these, they are junk!!!!!!!!!

This gamma lid was so difficult to place. I followed You Tube instructions, using a rubber mallet to seat the ring in place. It sealed all the way around except for one area, in which I finally got it to seat but I think the fit is poor. I can only get the screw top lid to unscrew open but am unable to screw it in place....I basically have to snap it in. The price was good but I am not impressed with the product. I bought two buckets and lids so I think I will return the other and find an alternative.
