I don't have this set in particular. I've purchased individual brushes from them. I have 10 and I love all of them. I've had them for over a year and I've never had an issue with shedding. The shipping is also really fast. They have great customer service. A lot of people rave about the morphe brushes because they are cheaper but I've heard that the customer service is terrible. If you buy this set make sure you use a discount code from a youtuber so you get money off :)
I have loved these. I believe my husband bought them for me 4+ years ago. I think I could replace a few of them but I wish I had taken better care of them and cleaned them more regularly. Sigma actually sells a mat that you put in the sink and clean the brushes on that I would like to buy ($25). My bristles have not fallen out and the brushes have not rusted. These have held up so much better than my MAC brushes.
