Product review (4 stars): Picture Needs Updating
They really should update the picture.  Picture shows the entire vent assembly.  This is only the cap.

Now, if you want just the cap, this is a nice one made of metal not plastic.  The packaging could be better to avoid dents and dings in shipment but after you install it way up on the roof, you aren't going to notice a few small dents.  The cap looks like it will withstand a few tree branches hitting now and then and after all, isn't that why you are looking for a new vent cap?
