I have been using this Revlon Colourstay Eveshadow for a long time now, but not because they're necessarily awesome. I don't have a lot of spare cash, and so I wanted to get an eyeshadow that was a pretty good brand, and funnily enough I wanted it to last all day. The 'Colourstay' was essentially why I bought it. I have the neutral pallet - same colour as in the brand pic above I think.
I apply with a brush, not the ridiculous pad things it comes with. If I apply heaps, I can get some colour. Not tons of colour, but enough to go to work. Not enough for a night look in my opinion. So, does it last all day? I can only say 'kind of?'!! I have paid very careful attention over the last few days as I knew I'd be doing this review, and honestly by the end of the day my eyes are just a bit shimmery - that's it. Maybe my expectations are too high, but what I was hoping for wad my eyeshadow looking pretty much the same at the end of the day as the beginning, and that has not been my experience.
I will say that as advertised, it does not crease.
So, now that I'm at the end of the pallet, I will be moving onto eyeshadow with more pigment and staying powder.
I have the 500 Addictive quad and I only use the dark brown eyeshadow on a daily basis. It's smooth and buttery and easy to blend. Pigmentation is alright but I generally like my eyeshadow opaque so I layer it on about 3 times. The reason why I wouldn't repurchase this is because I just don't need the other 3 eyeshadows. But for people who like neutrals, this would be the perfect quad. I'd definitely recommend this product.
