"Splat-tastic!"
Was dubious this would work, but it does the job perfectly. I'd previously used an old tea-towel to cover my stock pot whilst blasting the soup, but that usually ended in splash escape and a very messy tea-towel. But this guard has revolutionised blending. It withstands the heat from the hot stock pot, and is so so easy to clean. Buy one. You won't be disappointed.
