2019 Huracan 580-2
I am working with the supplier who is communicating with the manufacturer to see if we they will replace it. The supplier needed a picture but I sent a very short video instead. We shall see....The wobble is caused by manufacturing defects. The plastics are pulled out too quickly from the moldings. I wouldn't be surprised if it is made in China. Temperature can also cause the bottle to deform if the material is stored improperly or made with wrong composition.
That wine bottle caps is a good idea. I've never known they have the same size! I usually just use my hand to seal it temporarily before shaking it.
