I have the 'graped up' chubby stick and I love it as a neutral lip colour. It's really easy and pleasant to apply, and very moisturising compared to other lip products.
It doesn't stay on as long as traditional lipsticks, but it's not meant to and it's by far my favourite tinted lip balm as it has a bit more pigment to it.
Colours were quite nice ( watermelon and strawberry), balm effect reached. Did find that it dried my lips out - that whole, addicted lips effect. Would have been brilliant if it smelt and tasted yummy!
