I think this primer is a really good, affordable option if you are on a tight makeup budget. It's only a few dollars and you can get it from quite a few places online and also instore at Kmart.
This is really easy to use, you simply swipe a small amount (definitely go with a small amount, too much and it will crease) on your eyelids and then I rub it in using my fingers. I then like to let it dry for a couple of minutes before I put shadow on top.
For a while this was my fave primer and I loved using it to get creaseless eyeshadow looks and to help colours be a bit brighter. Then summer came along and my eyelids started getting super oily and gross and this just didn't cut it for me anymore and my eyeshadows were creasing after only a couple of hours. I started using the urban decay primer potion and that is magic for my eyelids so I can't see myself using this product again.
I would still recommend it to others though, if you don't like it then you haven't wasted a large amount of money and if you do like it, then that is great. It does also come in a few other colours so that is handy when you want to do different kinds of eye looks. The tube has a really good amount of product in (I'd been using mine for months and still had heaps left).
I got this as part of a haul just because I saw it was cheap and I thought why not. It's by far not the best primer I've used (Fav at the moment is urban decay eyeshadow primer) but it does what a primer is supposed to do. It does the job and holds the eyeshadow for much longer, makes the colors more vibrant as well as makes the eyelid smoother looking. Because it's colored, it actually makes has a very slight concealer effect, so that's a plus. The texture is quite nice, and application is easy with the wand, although I prefer to blend it in with my fingers.
