Vacucraft 4-Piece Vacuum Seal Lids Set

Original review:... What vacuum? Pump all you like, there is no detectable vacuum created. The lids are still just sitting loosely on top of the containers. I bought these for use on smooth rimmed glass bowls. If it won't create a vacuum on those, what will it work on?Amended review:I'm amending my review. Take a look at the orange juice image for this product. That's what it takes: a significant overhang for the lid. If you have that, it will form a vacuum. Since the lids come with no instructions, there is no way to know that a lid that fits - slightly larger than the container - will not work.Given the extra space required to store containers having a lid with a significant overhang, I find these lids to be of limited use. I suggest you get a complete vacuum container with a lid designed for it, and the same size as it. (Such the ones in the video shown with this product: the video doesn't actually contain any footage about these lids.)

I had these lids from several years and I absolutely love them, I use it on blenders to create vacuum for a perfect grind and I use them on almost everything. It has perfect vacuum, the only time the vacuum does not work is due to human error by not putting the liner properly. I would 100% recommend this product. Specially indians who have troubles with leaking blender jars because of the lids that come with. These lids are a perfect solution.

Very smart, turns any bowl into a vacuum container. Your food lasts longer, stays fresher, and tastes better. It is also very good for marinating, it really gets the flavor in there.
