Product review (2 stars): Poor quality and poor customer service
Purchased this and it was delivered quickly.  However, the product had a yellowed top cap with stress cracks. It had flashing that was not removed after manufacturing it which was all over it.  Obviously no quality checking and the tooling is old.  The company refused to replace just the top cap and wanted me to return the whole item for a replacement.  That would waste my time and money, when all they had to do to make me happy was to ship a new top cap.  But they didn't.  The product does work well however, but we'll see how it holds up in the winter.  Plastic could be brittle.
