Anyone used Climate First Bank?

I recently found out about Climate First Bank from a mention by the Liberal Redneck. Apparently, they invest in climate change, LGBTQ rights and education, amongst progressive causes. They also boast a really impressive APY of 5.3%. I'm strongly considering switching to them because I believe money is a powerful tool for change. At risk of naively jumping in too quickly, I'm curious if anyone else has heard of them, or more importantly used them for their banking.
