Review on Ozeri INSTAVAC Storage Container BPA Free by Karen Gonzalez

I've had a set like this for years and when it became unusable due to breakage or in a case of a puppy chewing I had to replace it. The problem was that there was no hallmark anywhere on them. It took me a while to find them that are essentially the same with a few differences, mainly side zippers. Having just received them, I assume they will work the same way. Sometimes they hold pressure, sometimes they lick a little. I've found that a bit of olive oil on the rubber helps a lot, which I had to do from time to time with an old kit. Thing is, when they work, things stay fresh, and when they don't, it's like regular storage containers. You really can't lose and the price is right.
