Your grandmother wants this for Christmas. Be a good grandson or granddaughter and get it for her won’t you? This gadget is so much more than just a giant mech-suit for your jars. It can help those with arthritis(and the weak) open jars with ease.
The rest of us can just use cloths or run our jars under hot water. And if your jar doesn’t fit in this huge contraption, you probably should ease up on your food portions. Come on, grandma deserves this. Whether she can figure out how to use it is another matter entirely.
