After reading all the great reviews on this product on Amazon, I decided to go for this. I don't typically have good results from diet products, but I figured I'd give it a shot. I've been taking these for 3 weeks, as directed, and I might as well have been taking sugar pills for all the more this is doing for me. I felt like my appetite increased, I haven't lost any weight at all - in fact I've been fluctuating up and down 3 pounds for the past couple of weeks. I gave this two stars because I didn't feel the anxiety or sleeplessness that some people complained about, but I'm still disappointed. I was hoping I'd find something that actually worked!
Negative

I got these for my jawbone headset. Many had said they work great. but for the life of me i cant figure out how you get them to work short of superglue and even then they are too quiet to hear so i guess they work on the jabra they are designed for but not the jawbone.
Negative

It worked well for a few weeks, but then the battery of my iBook G4 stopped being re-charged.
