Didn't work for my cats.
I don't doubt that this product works for other people's cats. It did not work for mine, however. They both became super aggressive with each other and other cats in and outside the house. It made them restless, coming in and out of the house all day. One of them started crying incessantly at night and the other still peed on things. They went back to normal (well, as normal as they get) when I unplugged the diffuser and opened all the windows. I think it's worth the price to try this product, but don't be surprised if it doesn't work or makes things worse.

I'm impressed!
This product worked spectacularly well in my house with 6 cats in 2400 sq feet. With two males (neutered) and four females (not spaded) we have had constant problems over the past three years with cats spraying areas to establish territoriality.

We have 10 litter boxes scattered about with 3 or 4 different types of litter (more than the n+1 rule), but this hasn't eliminated the problem. I've tried isolating cats with their own litter box, and although this helps it also didn't solve the problem.

About three weeks ago we installed 6 diffusers throughout the house -- particularly in areas where the cats constantly soiled. The result was almost immediate. They stopped urinating outside of the litter boxes. In only one instance has a cat urinated, and that was in a room we normally have as a cat free zone.

The problems caused by having the second male cat hasn't disappeared. He is socially immature and tends to attack the other cats, but the stress levels for the cats have gone down.

I wish we had known about this product sooner. Other than its cost, which is a problem, Felliway does what it claims and I will be using it from now on and am an enthusiastic endorser.

Feliway diffuser calms aggressive cat
My cat was indoor/outdoor for 10 years. An unexplained midnight injury resulting in the loss of her eye has changed everything, and now I lock her in every night. She is angry, every night, and had actually started attacking me. I hold the cat right by the Feliway diffuser and pet her, and she is now her normal loving self, rubbing against me and purring. This stuff works for calming--I don't know about the marking as that wasn't my issue.

What's The Big Deal?
So, I bought the diffuser just about a month ago and I am not really sensing calmness in my cats. I think you have to put a diffuser in every single room of the house, but I hate to spend that much money if it still doesn't work.

Cat only sprays once in a while instead of every day.
I must qualify this by saying I have a sociopathic cat that is very tempermental and uses the living room carpet as his marquee sign to communicate with me. Because of that, I have two Feliway diffusers and they have significantly cut down on his spraying. It hasn't stopped altogether, but at this point a reduction is good news. So, I would recommend this product.
