Product review (5 stars): Not Complete based on image
The image displayed of the contents is a bit deceiving apparently.  It does not include the clear tube with the hex connector nor the metal o-clamps.  I returned the original package because of this incompleteness, however the replacement was an exact replacement, so don't expect a complete package.  I went ahead and ordered the clear tube which is roughly $10 more, so it's not that big of a deal and the price here beats whatever you can find elsewhere, but just beware.

[UPDATE]
After contacting customer service they opened an investigation and I was able to return the second incomplete package and received a fully complete package. So now I've updated to 5-stars.
