I have been hearing about this mask for a long time and finally decided to purchase it. The jar is tiny but you need so little amount of product to cover the whole face that it lasts for a long time. I have been using this mask at least once a week and after 1st use I already saw the results. My face looked and felt cleaner and my pores looked a bit smaller. The only thing that I don't like is that it's hard to remove the mask after recommended time it stayed on my face. It gets a bit messy to do it in the sink so I'm always removing it in the shower. Its easier to wash it out with stream of warm water than to remove it with a damp cloth (special one for mask removal I got for another clay mask).  The mask is not irritating my sensitive skin and it helps with breakouts and also works well before using AHA/BHA exfoliants or before using sheet mask. Over all, I'm quite happy with this product, just the removal gives it one star less.
