Interesting to hear about other 7570's. I got one of the first one's made. I know there were a few upgrades to software on the "newer" ones that weren't on mine. My bobbin light flashes and lets me know the bobbin is low and the screen will tell me. I press the OK button. I then have 15 feet of thread left and it will sew with the bobbin indicator light lit up. I like my indicator a lot. I know what that flashing light means even if the screen didn't ask me.
