Although I'm not happy about the high cost to replace a blendtec jar (wish it would be in the $39's), even when discounted, I am quite happy with the larger capacity and shape of this jar, compared to the original jar.  I often make thick smoothies for my children, and the liquid is less likely to get stuck in this jar.  It is also more aesthetically appealing than the original narrower boxy jar.

Not a big deal...I'm not sure why the top hole shrunk so much though (I take the whole top off when I wish to unstick something and/or stir).  In any case, I wish the cap would stay on more tightly.
