Input:
First of all, marination via vacuum in my experience and after considerable experimentation, is overrated. I ended up using this product as a differently-shaped option for vacuum storage, and went back to marinating well in advance.
As a vacuum storage device, the "instant marinater" has two deficiencies. The shape is awkward, reflecting, undoubtedly, the primary design need, to allow space for the bottom of the rubber cork. The rising arc of the top makes it impossible to put anything else on top of the marinater (except for other marinaters: they nest.)
Secondly, the design reflects the basic technical limitations of the vacu-vin line: the plastic is only strong enough to support a limited vacuum. I broke my marinater by overpumping. The plastic on the bottom seal (where it's thinner to allow for solid-contact nesting with other marinaters) separated.
Rating: two stars, not one, though I recommend, obviously, against purchasing this particular product.  But I still heartily recommend the rest of the line.
