Input: Consider Input: Thought this might be a nice alternative to use with my favorite coffee, but was sadly disappointed.  It leaked all over - no matter what we tried and the coffee was weak, machine clogged with most attempts and water wouldn't brew thru.  At times the cup even melted a little - leaving a nasty taste in the coffee.  Go with the greener alternative and try the ekobrew - much better results and no waste.

Input: Consider Input: Stonewall Kitchen Farmhouse Pancake and Waffle Mix is definitely a mouthful in name but, in taste, not so much.  Don't get me wrong, it's not bad but, you could find any number of "mixes" that taste just as well and some even better.  I know my taste buds aren't the same as yours so, what's just decent to me may be great to you.  I also wish I had bought just one can instead of 2 huge 33 ounce cans.  I finished the first can, I'll give the other can away and, I'll continue trying other mixes until I find the "best mix" out there.  So far I seem to only be satisfied with a homemade mix for my waffles.  My preference is for waffles over pancakes but, this didn't make it on either count.  I even tried adding things to it but it didn't really help.  Maybe it's just me.  Try it if you like but remember, buy only one can just in case you're like me.  You can always buy more.

Input: Consider Input: This is the first time I've really been misled by other reviews on amazon. I like 5-hr Energy, I find Rain ok and so I thought I'd try this product based on the reviews. Boy am I sorry! I gagged getting one bottle down even with my nose pinched (really). And it leaves the worst medicinal taste in your mouth afterwards. 8 tic tacs at once did not get rid of it! But worst of all, within an hour I was yawning and drowsy. Unless you really like things that taste of a weird tea-flavored cough syrup and don't work, don't buy this! I don't know what to do with the other 11 bottles. big fail
