Eyeshadow Primer - Best make up investment yet!

After attending an Illamasqua make up course and starting to practise my new techniques with smokey eyes, I wanted to share a product review, now I've been using it for a while.

Mac's Paint Pot in Soft Ochre, used as an eyeshadow primer.

It's a creamy eyeshadow, which Mac recommended to me when I went looking for a primer. My eye make up tends to crease after half a day, and as I wanted to start wearing more eyeshadow, I knew I needed a good core base product.

Poor quality pics from last night, but I just wanted to say that the Mac Paint Pot really makes me eyeshadow (even cheap ones) last perfectly. I like how groomed my face looks with eyeshadow on. Have you tried a primer?
