I purchased this as I was curious about pore filling primers and didn't want to splurge on the Benefit one.
This is definitely good for minimising pores - it makes your skin feel silky smooth after application and your foundation just glides on over the top of it. I did find though that my foundation did apply on my nose quite patchy, but that may have to do with my application of the product. I find it works best when you use more of a patting motion to apply it as opposed to the usual circular rubbing motions you would use when applying moisturiser.
The only con is that once you've almost finished, it does get a bit hard to squeeze the last of the product from the tube, but that's not a biggie.
I grabbed a tube of NYX Pore Filler when I was in the States and wanted to give it a try, being that it is considered a 'drug store' brand... and I am so impressed with it. It is comparable to the more expensive brands if not better!!
It comes out of the tube slightly clumpy which can be a bit daunting when you first see it, but it smoothes out onto your skin so nicely, and I love how it feels on my skin.
Hands down the best primer at a great price!
