My first impression of the bar is that it is really cute. It's got these little stickers that say "Do Not Eat!" so you don't mistake it as a candy bar... which I think is so funny. The bar itself is a decent size and since you use 1-2 per bath it can have up to 8 uses.
Speaking of scent, the Fizz Bar scent was very light. I liked it because other scents can be layered on top of it, but it may be a bit light for some people hoping for a total, whole-bathroom scented experience.
Would I buy these again? Probably. They aren't too expensive and they add a bit of luxury to the bath, which I'm into. The scent isn't overpowering which is good, and they soften the bathwater. I thought the product was fun to use, and while it wasn't the fizz experience Lush has conditioned me to expect, I'm okay with it.
