The design of the rack needs improvementI order the 20pc and it only had 14. On the package was a sticky note that read missing 6 bags. So it wasn't even the full product. I wasn't gonna complain but then I kept going and 3 out of my 14 had a hole. So I only got 11 usable bags. Kind of frustrating.Although these are BPA free, that just means a company usually uses an alternate plastic (like BPA-A) that's worse, but hasn't been classified on the toxic list yet. I spent 4.5 wks searching specifically for Silicone based "sandwich bags". I KNOW I ordered silicone, not these bags. My husband opened these when they arrived, washed them and meal prepped the dogs food for the week before I had a chance to see the packaging. I only just realized what I received when returning to complete this review. I'm disappointed I'm unable to return these, being not only used now, but the packaging has gotten wet (yes, we still have it).Anyway, if you're not concerned with the material these are constructed of, these are pretty solid. The "zipper" that closes these is leak proof; these do a great job when used in the freezer (they don't adhere to the food we've stored in it), making pouring out the contents very easy if u need to defrost the food in the microwave (DO NOT MICROWAVE food in these). The drying rack has proven to be invaluable. There are more than enough of each different size to suit whatever you need to store. I was impressed. Overall, I would definitely give these a high score, just wish they were made of silicone.Many sizes for just about everything. Easy to use and I like the little rack that comes with it. Just don't ever put them in the dishwasher like my husband did because I couldn't get it to seal after that so had to throw away. Definitely has helped with having to buy baggies all the timeInitially these bags were amazing. Sealed easily, cleaned easily (I washed by hand only), and did not absorb odors from food. Unfortunately, now the seals are failing to close, not sure what changed but it has only been a couple months and I have several that do not seal anymore. Very disappointed as they will now have to go in the trash....I will not purchase this brand again.I like the concept behind the bags being reusable and I guess the delivery carriers also liked the concept. I received my package as shown with mailing label adhered to the product package, but it was completely open and I was missing 2 of the 4 large bags. The box wasn't crushed like it was squished in transit, but rather someone deliberately opened the package and decided to take a sample for themselves. Of course, it had to be the large bags that I needed for storing leftovers in. A suggestion would be to ship the product in a discrete manner that doesn't advertise what's inside of the package, which hopefully would deter nosey people from helping themselves for free to your goods that you paid for. Elsewise, it looks like a pretty decent product.I had some different, more heavy duty silicone bags that had a "bottom" in them. These don't stand up, they don't wash well in the dishwasher - they won't stay open for the water to go in. I am very disappointed and will not be using them. The drying rack is very cheap and wobbly - falls apart when you take the bag off of it. I will stick with the other brand that is built much better!I wish I had found these Silicone Reusable Sandwich Bags years ago. I won't be wasting food any more. Now that I have these bags, I prepare meals to last me a few days, I portion my daily meals, organize and freeze them using these bags which come with an organizer. The organizer keeps the freezer bags uncluttered; providing more space for other items. When I take my individual meal out of the freezer, I let it defrost, I warm up my meal and I am ready for a feast! I absolutely LOVE these bags with the organizer! ziy
