Food Vacuum Sealing System with Hand Pump - Airtight Seal for Jars, Bags & Bowls | Battery-Free, Portable Vacuum Sealer for Kitchen Storage | Perfect for Meal Prep, Sous Vide & Food Preservation

I can't believe how EFFICIENT this little thing is! It can produce about the SAME vacuum as the electric device that sits on my counter used for the storage bags!!! I'm not joking here, people. This thing WORKS!The way I get MAXIMUM vacuum (I feel) is by actually PULLING towards the end of the vacuum cycle. What I mean is, I don't just pump DOWN all the time. I wait until the vacuum is about where it should be, then I give it several more push downs, followed by sharp pull UPS ... DOWN - UP - DOWN - UP. I feel by sharply pulling UP between say the last five-to-ten downward strokes I am producing the best vacuum possible. All I KNOW for sure is this thing works GREAT for vacuum sealing jars with a good sealing ring in the lid.Using a pickle jar, making sure it was completely DRY after washing it out, I filled it with my FAVE nut, pistachios, put the lid firmly on, pierced the hole in the cap's center, placed an included seal strip of the hole, and then pumped away like my life depended on it - lol! This was about EIGHT months ago (I did not have mine yet; borrowed friends!). When I open the nuts a few weeks ago - FRESH AS THE DAY I PLACED THEM IN!!! I purchased MY pump that same day.IT FRIGGIN' WORKS, PEOPLE!OH! OH! There is this EXPENSIVE device you buy JUST for wines, that you use to create a vacuum in the bottle after you use say just HALF of the wine, and this is SUPPOSE to keep the wine fresh WAY longer than an opened bottle should... you've maybe seen this advertised, right? Well guess what? THIS PUMP can be used for the exact SAME THING! And our little pump cost WAY less than the dedicated thing for just wine bottles. I have used this mentioned application ONLY for the screw-cap types of wines, but I have heard of others using special plastic or silicon disks and a 3-D printed 'interface' that goes between the pump and top of the wine bottle's end that the disk sits on top of. When you PUMP, the up-stroke raises the disk, which pulls the air out, and when you press DOWN the disk is sealed onto the bottle opening by the vacuum. You have to make sure everything is CLEAN and the disk fits/seals well.Now, get yer butts out there and go get your own before they are all sold out! GO! GET IT! NOW!!! lol
