This is a close second to my all-time favorite, Jack Links Beef Steakhouse Steaks, which is the filet mignon of beef jerky. They're very similar in taste and price, but the Steakhouse edges out this one oh so slightly. Still pretty awesome jerky, very tender, and not a hint of fat or gristle. Bon appetit!

I loved this mold!  I wished I could have used it for more than one occasion, but it didn't last.  I did use it to make 30+ suckers for my daughter's first birthday. But there was going to be no way that the mold could be salvaged after that.  I would have liked to have kept to use on other occasions, but for the price it didn't matter to me that much.  It served it's main purpose :)

My girlfriend loves grapefruit, but I absolutely hate the stuff.  For her, it starts and ends very sweet, for me (and most people in the world) it starts sweet and ends bitter.  After we tried the <a href="http://www.amazon.com/gp/product/B001LXYA5Q">Miracle Berry Fruit Tablets</a>tablet, there was a small difference for both of us.  For me, the bitterness subsided a small amount-- not even enough to worth mentioning.  For her, the grapefruit tasted like one of the "sweetest" ones she'd ever had.  However, the real treat for both of us came with the lemons and limes.  Both of which tasted noticeably better.  However, the effect of a single tablet wore off completely within 5 minutes.  To be honest, I hoped each tablet would last closer to an hour, but as is, you're paying quite a bit per minute for these things (we paid ~$20 for ten tablets w/ shipping).  Would I try it again?  After the tablets we have left are finished, I think not.  I already enjoy gala apples, bananas, watermelon, oranges, and strawberries without this tablet-- I can live a perfectly happy life without ever eating grapefruit, lemons or limes DIRECTLY (lemon and lime are fine in foods).  If you're dead-set on trying these tablets, try it with some of your friends, but don't expect too much.
