Review (4/5): I am pretty happy with the purchase
For what I paid, I am pretty happy with the purchase. A few of the labels on the brushes were mislabeled or mixed up, but that's not a big deal unless you don't know the difference between a fan brush and an eyeshadow brush. :)
There was indeed a strong chemical smell/mothball smell. It was more prominent on the case than on the brushes. I had planned on washing the brushes with a brush cleaner anyway before using them, and would have washed them even if there was no smell, but after washing them the smell wasn't noticeable on the brushes at all. The case, however, was much more pungent than the brushes and I'm not sure how to make the smell go away. I'm taking the product page's advice to air it out, and we'll see how it works, but if anything I'll probably just end up wiping the case down with cleaning wipes to cover up the smell.
The bristles on the brushes I received were not falling out and none of the handles were loose. While washing them, I did tug on the bristles and none fell out at all. There were some stray bristles/bristles that were longer than the others, but it was no big deal. I had to trim them, so that's a very easy fix.
No, there isn't a brush for every occasion, nor did I expect every kind of makeup brush known to man in the set. Look at the photos if you want to know what brushes are included in the set. This is a good "basics" set. I purchased it solely to replace some of my everyday brushes that have seen much better days, and I don't like spending a lot of money on brushes from big brand-name companies, I'd rather save my money for good makeup products.
I've used some of the brushes and they get the job done. The pony hair and face brushes pick up product very well, so I'm happy.
All in all, for such a reasonable price, this was a worthwhile purchase.
