Every other mascara will smudge on my upper cheeks (when I smile my lower lashes touches my upper cheeks). This product has never failed me, regardless of length of wear, temperature of day, or how much I'm laughing. It's also easy to remove: comes right off when I use makeup remover cleanser and warm water for the rest of my face.

This mascara for the price was a let down for me. It does add mega volume, but the lack of length and separation gives me stubby and clumpy lashes. I did finish this mascara up by pairing it with a lengthening mascara, but will not repurchase.

Mixed reviews about Opulash - one coat and I find it colours my lashes nicely and adds some length, however I want more length and a second coat is a definite no go as I tend to find it looks really unnatural and goes clumpy. Spending £20 on a mascara, I would expect more. Added to the fact it's not waterproof, I award this 3 lippies and will continue my search for the perfect mascara! 

My first MAC mascara experience and very pleased! Lengthened, volumized, zero smudging after 11 hours, and easy wash-off removal. Curl hold is so-so and it does clump after 3 layers, so off 1 lippie. I have short, spare, straight Asian lashes and every formula I've tried smudges except Lashpower by Clinique and now...Opulash! It delivered decent drama, about a 7 on a scale of 1-10. It's a nice all rounder mascara.

I regret this purchase, it did not deliver any effects, except some black cream on my lashes. And it smudge easily, i had to wipe my under eye line several times during the day. Save your 20 bucks for something else.

After being generally pretty disappointed with MAC mascaras over the years, finally they put out a mascara I actually love. It has a big brush that reminds me of the Diorshow brush. I was impressed by the length and volume Opulash gave me, it has a strong pigmentation too. I found it was slightly clumpy at times but overall a very good mascara.

I bought Opulash instead of False Lashes and found it to be really clumpy. The bristles are fairly rough and don't grip the lashes well, and in turn you have to apply a second coat, causing the lashes to stick together. I work in makeup and got a few embarrassing comments on how bad my lashes looked the day I wore it - I'm sure it would work for some people but I have long lashes and I wasn't too fond of it, and usually I'm a fan of MAC mascaras.

I just picked up some Opulash for my first time last week with one of the new MAC holiday eye sets. I was needing a new mascara and am normally happy with MAC so I figured I'd give it a try. Opulash is very lengthening, and holds some nice curl too, it also helps separate nicely, and the colour is great, I have this in Bad bad black and it's very nice and dark. The only hangup I have is that it can clump if you're not careful, as the formula is quite thick, but if you are careful about wiping off the brush, you'll be fine.

This has to be one of my favourite Mascara's. My eyelashes are quite short and some of the most popular mascaras do nothing for my lack of volume. This mascara however makes my lashes look thicker and somewhat longer, not to mention it lasts all day and looks as flawless. My favourite mascara by far!

First MAC mascara, but I really like it. It thickens my lashes without getting too clumpy. It is not waterproof but stays where it is supposed to, even in humid weather. Plus: I can remove it with only water or cleansing lotion. When I ran out of it I repurchased the Optimum Black version which I find a bit dryer but also very nice. Will repurchase one of them again.
