Pros: Compact for diaper bag, easy to use, washes well, good value
I bought these when my son was born and we used them for 18 months as our wet bags in the diaper bag. I bought them from Amazon and the reviews there are fairly mixed, too - so I don't know if I just got a stellar set of them or what, but I have no complaints!
These bags are sized for tossing a couple diapers (maybe two toddler size, three infant size, four newborn?) in the diaper bag. We washed ours with our diapers on hot in Country Save detergent. We ALWAYS line dried. These bags cannot go in the dryer, ever. They will get ruined and 'gummy' as other reviewers mention.
Overall, I've been happy with these bags and we will use them again for any potential future babies!
