This is one of those products that takes the cake for me. Not only is it cheap, it's an amazing product. My only down side would be the packaging. I am not lid - mine seem to come of and break every time. Regardless, my skin is oily and this product is perfect. After applying my foundation with a beauty blender, I 'dot' the powder all over my face using a blending brush by RT. It sets my foundation and gives me great full coverage. It also makes an excellent base for powder bronzers and blush.
I took it with me on holiday to Vanuatu and it even withstood the heat and stopped the rest of my makeup sliding off my face!
I love this powder! I use the translucent one and it's quite cheap and mine has lasted me for months and I use almost every day. My t-zone (especially my nose) is quite oily but this keeps my makeup in place for the whole day. By the end of the day, my nose is a wee bit shiny but at least my makeup hasn't completely oiled off.
