My 11 month old Welsh Corgi figured this out the first time she took it from my hand.  However within a matter of hours she had the rope soaking wet and chewed mostly in half.  The rope is now soft and not a useable tool to get the treat out.  The knot was also too big and frayed to let any of the snacks out of the bottle.  You should also know that the snacks this company makes are too big for the extra small bottle.

Ex Output:
Negative

This tea is very good.  I discovered it while visiting in California. The moment I got home I searched local stores for it and I was not able to find it.  Finally I decided to see if Amazon had it and they did and I bought two boxes.  As long as they make it I will buy it.

Ex Output:
Positive

We have this model about a year now.  It hasn't worked right from the beginning.  We often had trouble closing the top.  Sometimes it doesn't work at all.  Other times it works like a charm.  When it works like a charm, it's not uncommon to find coffee grounds in the cup. It's a mess.  I bought the same model for the office. The experience was similar.  Sometimes it makes a full cup of coffee other times it doesn't.  Sometimes it won't even work at all.  We have to turn it on and off and cross our fingers. A friend reports these problems as well.  I agree with the reviewer who says, DO NOT BUY.  A waste of money for the machine,for the K-cup that couldn't be used, and an exercise in frustration. We're in the market for a different brand.  When Keurig first came out, they had the market.  They have a lot of competition now . . . which hopefully will make it easier to find a machine that works well.
