Pros: Seems to take the edge off and gives the cats a sense of calm and security.
Cons: A little pricey and mine seem to run out after about 25 days. Diffuser tends to get a little warm in the outlet.
I gave this 5 stars because these diffusers have always worked for us on numerous occasions. I tend to use them when I foresee an upcoming stressful event for the cats such as: out of town company, moving furniture around, any outside stressor that I can predict, and for my one bully kitty who likes to tease. I recently had to move some litter boxes around to different locations and used the diffuser during a one month transition. I found that not only did it help with the change but Wendall's urge to tease seemed much less. My other cat, the one who get teased, always seems more confident when I have a diffuser plugged in and less likely to get upset. I don't use them all the time just on a case by case basis but certainly glad to know they are always available for back-up with any stressful kitty situation at home.
Pros: we can not smell anything
Cons: cats do not care about it
I was suggested two years ago and bought several bottles trying to prevent one of my young cat to attack my elder one. We never feel it works for us.

Pros: The feeling that we were doing something
Cons: No measurable improvement
I first purchased this product about a year ago when a female cat, I had hoped to adopt, insisted on urinating against books, plastic bags, in the kitchen and on the stairs. I installed 3 diffusers around the house: in her room, in the hallway and in the large living room. I refilled them once but, since there were no changes in this cat's behaviour I did not renew them a second time when they ran dry. We rehoused this cat in a one-cat household and her well-being and behaviour improved immediately.

The second time I purchased this product was for a large room in the cellar (one diffuser) to try to calm a cat which loved to bite. In the space of 2 months there was no improvement in his behaviour and the diffuser was again only refilled once. I cannot say that I will never buy this product again as situations with cats are never exactly the same and, who knows, perhaps Feliway will work positively on one of my fosters one day.

I use one 24/7 too, I keep it plugged at the door where they all (seven) can go in and out into their cat proof fenced back yard, no more arguments at the door.  They all file by and quickly smell the diffuser like it is a required activity to go out the door!  Very cute!

Stephenietx is right; it doesn't work for all kitties.  I have a 12 year old male that went into full stress mode when I brought home a year old male, not neutered yet 2 years ago. Since I'm retired, I'm home to supervise and run interference day and night. finally after a year, the older male was tolerating the now 2-year old younger male and also he was neutered shortly after we got him.
We had a female that passed away at 10 years old and I adopted and brought home 2 female kittens a year ago and was ready this time with Feliway to calm down my older male.  Well.....let me tell you....we rushed him to the vet's twice with emergencies because I thought he was choking and something must be caught in his throat. At the second visit and a different vet, he diagnosed acid reflux from stress.  His throat was raw from stomach acid. Feliway worked the OPPOSITE!  He SAW 2 new kittens, he SMELLED maybe 10 or 20 new cats and I'm sure he thought he was in danger.  The Feliway, in strategic places in the house, made him think there were MANY new cats and he reacted.  The vet gave him a shot of something to slow or stop the excess acid and I got tiny pieces of human acid reliever pills to give him.  A year later, he is back to normal except for sometimes playing a little with the kittens.  He won't play with my other male.  And here's the kicker. When I got my 12 year old male 10 years ago, he was 2 years old and was in a cat/kitten play room with about 15 other cats. I'm sure he was placed there because he got along with other cats so well. 
So now I just hold onto the Feliway and will only use it with any of the other 3 cats if they have to go to the vet's in their carrier.   I won't use it on my older boy AT ALL.  It had never occurred to me that it would work the opposite on my one cat.  The vet was surprised, too, when I suggested what must have happened.

We used the Feliway diffuser numerous times when we had guests staying with us or were away and had a cat sitter for Jamie. He was always a rather hyper cat, and the Feliway worked wonders.

I use a diffuser in the hope the 2 out of my 5 will become less terrified of people. They do eat in the room without problems, but are still to timid to touch. I got the spray for my hands too, but they don't seem influenced by it. However I find that quite a few other cats come in, don't pee any more, but make themselves comfy, even though they have homes of their own! It causes some fights, and on Big Bad Tom actually killed one of my cats, newly spayed, the mother of the 2 traumatised kittens (6 months old now!). I gave the girl the pill, but I'm not sure if she's not pregnant now, so I need to catch her for an examen at the vets. They're all fat, and the last 2, the "timids" are very furry, so it's impossible to tell from looking. I wish Feliway was really miraculous, although it does help some, I need a miracle (or a selective cat trap!), These 2 little ones are really resistant to all approaches. Wish us luck...
I am surprised that you had a poor outcome with this.  
I have done reviews on both the plug in diffusers and the spray on this site , but I purchased and used the Comfort Zone ( with Feliway ) so its from a different manufacturer.  I have heard that in about 5 % of cats, it isn't effective.  But in 95 % of cats, it is effective.   Comfort Zone is the only brand I have used.  And you have to check the expiration dates, too. 
I found that with inapprorpiate urination, you have to not only do the plug ins but also the spray, and spray it every 12 hours in the offending areas.  They say to keep it up for 30 days, every 12 hours, but honestly, I did it for 24 hours and my cat stopped spraying.  We stopped spraying and he started marking again.  
So we then kept it up for almost two weeks, spraying every 12 hours for 10 days, then went to once a day for the balance of the time and he hasn't peed there since.  
It is good stuff, but fails for a few cats here and there from what I am seeing.  Hey it is worth a try because thousands of people have had good luck with it and if it works, it saves the cat from being re-homed.  
In your case, sounds like your solution worked out for everyone, anyway.
