I have used this product for months and have been happy with the performance. The bags will get "sweaty" after a couple of days if there is anything moist inside them because moisture from the compostables begins the process of decomposition. Be sure to change your bags regularly (say, every 2-3 days) and they should hold up fine. I also recommend first putting something dry in the bottom of the bag like a paper towel that you are going to be composting anyway. The less direct exposure the bags have to fluids, the longer they will keep their integrity.

I have yet to have one of these bags fall apart or develop a big split on me. In fact, the only holes I've had so far have been from pointy things like wood splinters from disposable chopsticks I've broken into pieces.

Have used this product for years for kitchen wet garbage.

I use these for my scraps so I can compost them without getting the trash can dirty.

We participate in our city's composting curb pickup program. They require CMA approved composting bags (for those who use bags) and have certified that these bags meet the CMA requirements.

Update: Changed from 4 to 5 stars. I had originally reported that the bag 'weeped'. Two bags later, with the bags accumulating actual liquid over a week's time, I'm convinced I was wrong. The bags do not weep.

It seems that there is no perfect compostable bag: every one for sale on Amazon has a fair number of one-stars.
I keep a small compost pail - lined with one of these - in my kitchen sink, and I throw all compostable waste into it. Usually I fill up a bag in about five days. And usually it has a fair amount of moist waste in it.

I had previously bought Glad OdorShields and they worked fine for me: even at the end of a week I could twirl the top of the bag and lift it out of the pail with no leaking and no tearing. But the Glad bags were more expensive than these, so I decided to try these.

I've used them for a couple of weeks. I just now closed the top of a bag that was full to the brim and had sat in the pail for six days. It did not tear - so in that respect it was as good as a Glad bag. And it did not drip. But there was a small amount of liquid in the bottom of the pail - as though the bag had 'wept'.

The weeping is not a problem for me, but that's why there are only four stars instead of five. You'll have to decide for yourself whether the Glads are worth the extra cost.
