Anyone take Raspberry Ketone supplements?

I was just reading an article on Dr. Oz about "5 Fat Busters for 5 Body Types" (http://www.doctoroz.com/videos/5-fat-busters-5-body-types) and he recommends taking 100mg of raspberry ketone supplement at bfast.

If you don't want to read the article, here's what it says, "Raspberry ketone, a natural compound found in red raspberries, helps your body to burn fat by breaking up fats within your cells. It contains the hormone adiponectin that boosts metabolism. The supplement is recommended because you’d have to eat 90 pounds of raspberries to get the same effect. Take 100mg of raspberry ketone at breakfast time. You can start to see results in just 5 days and more dramatic results over time. You can find it online and in health food stores for about $12."

Does anyone here take it? I'm interested in it but would like some info from real people who have taken it first.
