So I have not tried the original black one before, but I really wanted a blue mascara and this was the only one I could find. It was also very cheap online. I have no idea if the black one is better than this, but this mascara was meh. I didn't exactly expect a ton of volume or length or anything like that, I just wanted the colour. But I did, of course, have hopes for the formula of the mascara.
The colour payoff is fine, but the formula is very thin and it sticks to the mascara wand weirdly so that it can be kind of difficult to apply. It also smudges everywhere, especially if applied on the lower lashline. It flakes quite a bit throughout the day and it comes off extremely easily, but I'm not sure whether you'd call that a pro or a con. Overall it's okay, but I kind of wish I could've gotten better.
I used to use this mascara for years when I was young. At some point I wandered away from this brand, as there's always something new on the market and mascara is my weak point in regards to buying on a whim. Last year I bought it and used it again, having had fond memories of it when I was young I thought it would be a solid buy. I'm not sure why, but I'm not sold on it any more. My eyelashes are thick and naturally curled, so I'm not sure if thats it, but I found it really clumps. I used it quite a few times, in various ways thinking it was user error, but the result was always the same and I felt that other brands were much better on me.
