I love the product.  But, the bottle design is terrible.  In order to get the last 1/3 or so of the body wash out of the bottle in a timely manner you would normally store the bottle upside down.  With the pointy top that is impossible.  So, you must stand in the shower the try to shake the remaining product the length of the bottle to squirt it out.  This takes much more time that you'll want it to take.  Redesign the bottle with a flat top...please.

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.

I just ordered this, came today and thought I would just try it, well to my amazement,My little Daisy ate it and wanted more.My little Dog is just 8 yrs but has trouble with Flare-ups with her pancreas, I have to avoid fats and corn with her and she needs more fiber. I have been making her dog food ,but she missed eating the dry,I wondered if it was small enough for her to chew , but it was.
