A few weeks after my son was born I had to break down and buy a diaper pail and wanted a no fuss no muss kind. I did some research and found this one. It was nice because you can use it even after you don't have kids in diapers. A really nice feature about this is you can put a regular garbage bag in if you don't want to spend the $20.00 on the refills bags.
I'll admit that after a while that it will stink but what diaper pail doesn't stink after having nasty diapers in it for however long. I have found that if I use the flushable wipes once a week and let it air out for the night (if it's really stinky) the smell pretty much goes away. It's pretty much ready to use out of the box and it does work. I empty mine out once a week and really have no complaints about smell or anything for that matter.
I would suggest that you buy this if you are looking for something you can just take out of the box and use. Anyone can use it and my three and a half year old loves to throw away his sister's diapers. If a three year old loves and knows how to do it then you will too.
