Love my Hello Cup!
I've tried other cups, and now I've tried to a Hello Cup - I won't look back. It's completely game changing and by far the most comfortable cup I've ever tried. You have no idea it's in, and it lasts for hours. Also love the colours!
I've found the key is to get the fold right - Hello Cups use a 'shallow punchdown fold', as they are made of TPE, whereas most other cups recommend a 'c' fold, because they're made of silicone.
Love my Hello Cup, thanks!
