I bought this brush in México city long time ago, I used it almost non-stop for a bit more than a year. I got it with the Core Collection and from all of them this is the only one that I really used.
To be honest I am not sure what my verdict is here. It performs very well, I really like the finish. Now, why am I not sure about it? Well, it is ok quality, pretty good for the price you pay. I do not think you can get better quality for those prices. After using it for a year, a year and a half, you should already change it. If you are someone that does not wear make up regularly and you are not interested in paying high prices for a premium brush, you should definitely get this. Now, if you are someone that uses make up pretty much everyday, you will use it up quickly and maybe you should try to invest in a premium brush that lasts better longer. If you do not mind paying higher prices and do not wear make up regularly then definitely buy premium brushes that will last you a long time.
Would I buy this again? Not really, I would rather invest in a more premium brush, but this brush is very good quality, specially considering the price. I would say you should decide if you buy it depending in your make up habits.
