I signed up for a 6 month subscription. I'm 3 months in and have only gotten skin care products that I specified I didn't want. I literally haven't liked a single one. They all feel cheap and honestly I don't want to put them on my skin.
You can't cancel your subscription in the app, and the FAQ forms on their website don't help because the links don't work. The only option is to email the company and hope they get back to you.
I used Ipsy before and cancelled because I wanted to try a new subscription box. If you're in the same boat, I'd recommend staying far away from Birchbox.
If I have to say one positive, I do like one of the mesh bags I received with the samples one month.
