Bests & Worsts Reviews from Amazon

I've had my Ninja for about 18 months. I loved it. Used primarily for smoothies with frozen fruit. The other day it exploded on me and tore a hole through it. I have contacted Ninja. They didn't seem too concerned about it, and when I pressed them and offered to send them the defective blender jar so they could figure out the defect, they didn't seem very interested. The email they gave me was incorrect so I have to call them again to try and pursue this. I don't want another one, I just want them check it out because obviously there is an issue.
