Received quickly but 1 of the modules had a bent header. I was at least able to correct that. That one and another of the 3 have a broken inductor. Even though the 2 modules with broken inductors work, I do not know if they will last long with use. The 3rd module had no issues and works. Messaged the seller but no reply after 24 hours.
