I've heard such good things about this mascara but was reluctant to try it with the disaster that is Lash Stiletto in mind (I had to throw it out because I seriously couldn't stand the smell). Thankfully Collosal has no discerning smell whatsoever and unlike LS, it's a great mascara.
Fat brushes aren't for everyone but I love them, and this has a large bristle one which is great for gripping lashes at the root. As you can read above, it promises 7 times more volume in just one coat and no clumps. I can't say that I noticed 7x more volume but you can see the result for yourselves.
With one coat (top lashes only)
I am happy with the length of my lashes and prefer mascaras which provide volume. This certainly does the job as my lashes look much thicker and as it's waterproof, it lasts all day with no flaking. You do need a good eye makeup remover for the waterproof version or else it won't budge!
Is it worth the hype? I think so and I will definitely repurchase this when it runs out.
I bought mine for £6.99 at Boots.
