- The softness makes it easier to remove. You can more easily "remove" the vacuum because you can squish it better.
- The colours are great.
- It never leaked for me (unless it was over full but that is normal).
- The stem ist hollow which also makes it easier to squish I suppose but it also is a place that gets very dirty and hard to properly clean after a few years. It's possible with a qtip but in my last cup that was the place that changed colour the quickest. It's just the colour though! All hygienic and cleanable otherwise.
