The buttons on this blender have amazingly satisfying haptic feedback. They are fun to push and give the perfect balance of give and resistance. I don't use the programs much, and the jar is precarious as it sits on top. I like that it is glass and easy to clean, but as the jars base is half the size of the lid, it can easily be tipped over by a milk jug stuffing its way into the fridge. No spills or falls all year, but a bit of anxiety, storing in the fridge. In many ways I feel its better than blendtec, having a glass jar, the programs, the automatic sensors, the reversing blade technology, ease of cleaning etc. You can only get it at wallmart which is off putting to some, and myself, such a good blender should be available everywhere. Like every blender it needs to be quieter, a bit of foam on the interior could go a long way.
