This primer isn't up to par with higher-end products like Too Faced Shadow Insurance of UD Primer Potion, but it's a fantastic primer for the price. It holds pigment well and keeps my shadow on all day. It creases a tiiiiny bit after a few hours, but nothing extreme. For the price, you can't beat it. It's worth every single penny and it does the job.
I have mine in the clear "universal" shade, but it does come in colors as well.
I will note the only downside of this product is the packaging. It's both a positive and a negative that it's sealed VERY tightly - the lid snaps on and I have to use pliers to pull it off. Maybe it's just mine.
