This wouldn't work with anything you want to keep below that temperature, or for anything heat would destroy, but would this work, otherwise? I mean, if I had dried goods, shelf-stable, that I wanted to vacuum-seal in mason jars to extend the freshness/longevity, is there any reason it wouldn't work?
I only ask because it's good to have a backup in the event that the plastic toys break when you have a mountain of preservation to do. Heck, I was being flippant, but really, all you need is for the seal to fail, or for a crack to develop in the seam of the plastic of the pump cylinder, and it could make it impossible to attain a sufficient vacuum.
