I've used this mascara on and off for a while and have mixed feelings about it. If you are looking for natural looking lashes, it is good for this as I found that it made my lashes look nice and long.
I don't think much product comes off, and it definitely doesn't make your lashes look thicker (they look long & skinny).
I haven't really had any problems with clumping, but I try to wipe of excess product anyway.
I love the packaging of this, It sucked me in. and I did actually try this with another Maybelline brush and didn't hate it AS much, but otherwise, I genuinely hated it. The shape made it hard to find other brushes to use, and the brush it did come with was an odd shape, clumped my lases, and held WAY too much product, I think maybe the cleaner that's meant to remove excess at the top was not operating as required. Overall, would not buy again. Didn't finish it, and didn't even like it enough to regift to someone else. Do not recommend.
