Not like one I bought in 2008
I would love this product if they hadn't changed the design.  There is no on/off switch on it like there was on the one I bought in '08.  They want you to run it continuously but I never did, I always turned it off at bedtime.  The bulb lasted almost 5 years.  I guess they want you to order replacement bulbs more frequently :(  Now when I want to use it I have to plug it in and unplug it to turn it off---a big pain in the butt.  I would not order another one unless it had on/off switch.
