The flash speed is too fast, but it can be used. Now after a month of operation, the left side is buzzing and not blinking. It's too late to come back so all I can say is try another brand and hope for better results. These reviews are correct, other people had the same issues. I'm not sure if there's a flasher that fixes this, but the manufacturer didn't state it was needed.
