Wrong bulb in unit
Plugged in one of the units and I could hear the fan, but no light. Opened the unit to access the bulb; it was loose, so I tightened it and reassembled the unit. Plugged the unit back in and the light emitted was orange. Since a friend has one and all the pictures show the light as blue, I was puzzled. The instructions say the light may flicker or change color when the bulb needs to be replaced, but this is supposed to be brand new. Since I did order spare bulbs, I went ahead and changed the bulb, but noticed a significant difference in the sizes of the bulbs!? The one shipped in the unit was nearly a full inch shorter than the proper replacement bulb. So, not sure if the bulb was "bad" or just the wrong kind that someone snuck in with a return, but it certainly was not checked before...what? being re-sold?<br /><br />As to the product itself, we need more time to see if these units can handle litter box odor.
