It works, but only marginally faster
I recently brewed two kegs worth of a pale lager to test different clarification techniques. Biofine worked, but it was only two days quicker than cold storage alone. The beer used 34/70 which is notoriously powdery and hard to drop out, so it was a good testbed. I'll try it again on a different beer and see how it performs before I form a real opinion.
