Absolutely. I replaced the battery on a 2015 MacBook Pro 15" myself with one I bought from iFixit, who I thought were a reputable dealer, and one year / 150 cycles in it was swelling to the point where I felt it was dangerous to continue using the computer with the battery inside. I had a similarly bad experience with third party batteries on my iPhone 6S. I'm all for keeping things as user replaceable as possible, but personally I'm only using OEM batteries from now on.
