I used to have my MJ's hooked up to christmas light timer plugs (they're like 99 cents around christmastime). If this wasn't a test of a MJ in action I don't know what was. They cycled on and off for about 2 seconds each. I'm really surprised they didn't burn out. I used the timer plugs for about a year before I upgraded to Tunze 6060s.
Anyway, not that MJs can survive anything but I was always really impressed with them. I just wished they pushed more water
