I had the kind with a plastic slider on the top - I hated using them & they didn't seal well and things got freezer burn quickly. These seem to seal much better and are much easier to use, and the silicone being really clear so you can see the contents easily is very helpful too. You can fit a lot more in them than you think, I've been using the snack size more than I thought I would. I wish they would offer the quart size individually - I don't understand why you can get every size except that one. Definitely recommend them
These are great, but I wish they would offer more buying options. They only come in a 3-pack and they don't offer just the size you want individually. I am loving using these for work lunches and that they are safe to heat up in the microwave. They seal well and are heavy duty enough to be sturdy, but don't feel heavy to cart around.
I bought these to stop buying 1-time use Zip-Loc bags. They aren't quite as convenient to use or store, but overall MUCH better. I will buy more. I also bought another top brand but I am sticking with Durbl.
