I was so tempted to buy the full brush set due to the raving reviews on youtube however although i know its cheap against the MAC but i can't get myself to spend almost £100 on a brush set. Im pretty sure the prices have gone up too.
I do have quite a few mac brushes but still wanted the sigma ones until i could afford more MAC ones. I think ill just save up and buy MAC brushes when i can afford them then I'll have no regrets if for example i was to buy Sigma and didn't like them very much so yeah.
Sometimes, i never know wether or not to trust some of the reviews as these days all the major beauty gurus get everything free!
