Good product - very convenient
I got this at a good price. This does not merit the three star and below reviews. It works as expected as long as you change the bulbs once every year or so. If you live in colder climate, it is especially useful during winter time since windows are not opened often.<br />Couple of times my kid had cold and cough, I turned it on and that seemed to help.<br />PS: I am not affiliated to Germguardian in any manner.
