Query: HORRIBLE PRODUCT

I angrily threw away this useless piece of trash after using it once. I ordered it because it looked nice and sturdy, is made of glass, and had acceptable reviews here on Amazon. The first thing that annoyed me is that this bottle is shaped in a way that you need to hold it with two hands like a cocktail shaker unless you're a giant with huge paws that can reach around it. But you need your second hand anyway to keep the stopper in place, which has precisely zero footing in the bottleneck and falls out at the slightest of tilts, shakes, or moves, leaving a stain of salad dressing wherever it drops. Do not be deceived: This is a pretty-looking but very poorly designed product, and I strongly advise against buying it to save you a lot of frustration.
