[EX Q]: For those of us on a low carb diet these little tablets are just the thing.  Two years ago I started cycling again after many years but was having heart arrhythmia after longer rides in high heat.  I was drinking plain water but did a little research and thought electrolytes might be the issue.  Gatorade wasn't an option because it is so loaded with carbohydrates so I looked around for a low-carb alternative.  The "zero carb" sports drinks didn't help so what to do?  One day I ran across these at my bike shop so tried a tube of them.....voila!...problem solved!!  I've shared them with two friends in particular whose problems with leg cramps were resolved while using these.  These guys got it right -- they are superbly formulated and simply work.....

[EX Q]: I thought these would be the perfect answer. Sadly, I guess the pressure with which my Keurig machine shoots the water through the k-cup is too much for the disposa cup, because every single time I tried it, coffee grounds were spewed up through the tiny hole in the lid of the disposa cup all over the inside of where the k-cup sits in my keurig. And yes, I used them properly.  So the issue, at least in my Keurig machine, seems to be with the lids. Some have suggested its a design flaw with the Keurig machine. In either case, these disposa cups were NOT the answer for me.  Biggest waste of money ever. I cannot recommend.

[EX Q]: This is the favorite green tea in our household.  Been using it for years.  Was happy to find it here on Amazon, otherwise we had to travel about forty miles to an oriental grocery store to purchase it.  Can't even buy any leaf tea of any kind in regular grocery stores any more.  By the way "Ban Cha" in Japan simply means common or everyday tea.  Not ceremonial.
