It works just fine. Does what the ad said. But, now that I have it, I'm questioning when/where I'll use it. I did seal fresh washed strawberries in a mason jar, sealed it and stuck them in the fridge 5 days ago. They still look fresh so that's a plus.
Ok I’m going to add to this review - it’s now 10 days since I refrigerated these fresh strawberries and this is the photo TODAY! They’re as fresh as day 1. That never happens with strawberries in the fridge.
