Poor Design - Unusable
The plug just flopps around loose.  If we try to plug it in the wall, the plug pushes up inside so only the very tip of the plug will go in the wall.  That is not enough to hold it and it falls right out of the wall.  I have to put something up against it to keep it from falling right out. It is basically unusable.<br /><br />Update:  I took the "germ guardian" apart and found that the plastic inside the case that holds the screws for the plug was broken.  I was able to rig up something on the inside to hold the plug, so now we can use it.  It's really not designed to be repaired by the consumer, but I figured trying was better than just throwing it away.<br /><br />Now that it's finally running, I haven't noticed any difference, I can't say for sure if it does anything.  It is loud!  Sometimes I unplug it so I can hear the TV.
