Review on Prepara Evak Fresh Saver, Medium-Tall Airless Canister With Black Handle, 2.3 Quart, Clear by Richard Summerall

I can't believe some people are using this for guacamole and other wet items. (However, I must add that the photos of the food in the container only show dry food.)The bottom of the plunger is perforated so any gunk that touches the lid will get into the inner workings of the plunger! And there are a lot of inner workings on this plunger. There is the bottom plastic shell, an inner o-ring that is very hard to remove, the outer sealing flange, the top cap/handle and two umbrella valves. Because this product is so complicated, cleaning would take at least 15 minutes and half of my drying rack. Because of that I would only use this for something that is dry and non powdery. Maybe it would would be good for whole coffee beans, rice, and chips. Not flour, leftovers, or the such.Also beware when reassembling the cap (after cleaning the insides for instance) make sure to completely rotate the two halfs together. If they are not completely closed the air will easily bypass the two umbrella valves and you will not get any sealing at all.Lastly, I asked previous customers how hard it was to lift the plunger. People were quick to tell me that anyone could easily do it. I found the initial lifting hard and unsatisfying. It took about 4x force to initially move the plunger because the cup seal has to invert before the plunger can move. Furthermore, the whole plunger is able to wobble enough that the seal can be completely lost and the cup seal can be completely mashed!I think this is an innovative product, and you are certainly getting a lot of technology for your money, but I find this to be a gimmick at best
