It was doing great. I plugged it in, it was quite and doing great. The next day (yes, beyond the 12 hours it recommends being run the first use) unplugged it (had no on/ off switch) to clean out any bugs. There were no bugs. So put back together (back piece twists off) plugged it back in. Now it makes a very loud noise. Bad bearing (spelling?) In fan. This thing lasted 4 hours, that's it.
