I have been using this for a few months and overall I am very satisfied. The color lasts all day as promised without smudging. I am not one to reapply lipstick throughout the day so the ColorStay products are a must for me. The only thing I don't like is how it feels on your lips when applied, before the top gloss goes on. It is very dry and there is no way I could forget the gloss because wouldn't be able to stand the feeling. Another problem I found was if it gets on your teeth, you have to very quickly get it off before it has a chance to dry or you will be rubbing your teeth for 5 minutes to get it off. Of course that just shows how well the color will last. This was my first time buying this particular product and I will buy it again. It is one of the few lip products I have found that I can eat, drink and sleep with on and it still looks as fresh as right after I applied. it. Definitely a must have for me.
