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!

Ex Output:
Negative

About four weeks ago, I purchased at a Home Depot in Florida the Plasplugs "Master Tiler", model number: DWW180US-BX.I am using it for a porcelain tile installation. The original blade worked ok for the initial cuts, but I need to replace it for the proper blade type for the tile. I had bought a porcelain tile replacement blade from a blade mfr when I bought the saw. When I got around to replacing the blade, I found out that the Plasplugs machine uses a different "arbor" than everybody else. The replacement blade was worthless to me.I then called the Plasplugs US office to order the "high glaze" blade. Much to my chagrin, I was told the "all blades except the standard have been discontinued".I just bought this saw four weeks ago! I think it is very irresponsible for a manufacturer to behave in this matter.You can be assured that I will avoid any Plasplug product in the future.
