The filter is an Eheim Classic 2213.
The parts that are broken are the indented plastic pieces used in the locking mechanism (not sure how else to describe it)...along with some other smaller plastic pieces inside.
There is evidence that the box was dropped, most likely before shipping since no other products and nor the shipping box shows any signs of a fall.
We could glue these pieces we think, but since we think it was dropped, and just the way it was smashed, we are unsure of the integrity of the rest of the filter. So, better to be safe than sorry.
I e-mailed them Saturday night since it was so late. They responded Sunday telling me to call customer service, but I was on my way out the door. And I didn't come back last night til very late. Today, I am up at school all day, and have a class that goes til 9pm...so it's doubtful I will be able to call them today. Hopefully tomorrow night.
