Great Quality, I was a little concerned about the water leaking from the resevoir when putting it in, but that is not an issue at all, since it is quite easy to put the resevoir into the unit. It does have two small blue LEDs that are on top of the unit.
I have had this unit for several months now and couldn't be more pleased with it.
We bought one of these humidifiers about 18 months ago and it has been doing a great job of humidifying our 925 sq ft mobile home here in semi-arid Colorado. We had no room for a furnace mounted whole house humidifier, so this unit stands out of the way in a corner near the furnace cold air return and effectively humidifies the whole place. We have fairly soft tap water and had experienced no problems with using it to fill the humidifier until recently. Despite regular cleaning as directed, the scale buildup finally reduced the efficiency to the point where it no longer works. But Vornado is replacing it with a new unit under warranty anyway. What great customer service! The only problem during set-up was due to the manual saying things like "Refill reservoir to the fill mark" (there is no fill mark) and "The top of the reservoir has a flat surface that can stand by itself during the fill operation" (the top surface is not flat), and it talks about Low, Medium, and High settings (there are only Low and High) so the manual needs some editing. But the set-up was otherwise quite straightforward for someone able to follow instructions. My only ongoing complaint is that the LCD display fades to black during normal operation so there's no easy way to see when the unit needs filling. I'd love to see a LED to tell me that it needs attention! Would I recommend this to a friend? Absolutely! I already have to many friends.
I am amazed at some of the negative reviews that I read. Anyone who has ever owned a humidifier knows that it should be put on a flat surface, not on carpet or on a piece of furniture. I just bought the most recent model, and I have to say it is the best humidifier I have ever bought. I had bought from other competitors but due to the fact that the original companies were sold to others, the products are not the same. I bought this because Vornado is an American company and am familiar with the commitment of Vornado. I love the fact that the Vornado Vortex Action makes all the difference in the world. I have allergies and my apartment has hard wood floors and plaster walls that date back to the early 1900s. I even see a difference in my cats.They are breathing better- there is less dust and fuzz balls. It also treats my antique furniture and moistures the wood. Would highly recommend this product - easy to maintain and it lives up to what it is supposed to do! For anyone who has previously owned any kind of humidifier, the instructions are clear and as long as you follow them and treat the unit gently, you will have it for a long time. The company would not guarantee a 5 year warranty if they didn't think it would last. I have several Vornado products and they are the best!
