Product review (5 stars): Worked great!!
Worked great !!!  I had to do 22', so I purchased 2-sets.  heavy duty enough to get lots of service from it. Well WORTH THE PRICE...
Be sure and TAPE the joints as the instruction's state's. The reason for the tape as I see it is, the joint is stronger and going through the 90 corners. When your done you will need pliers to unscrew the joints, they get torqued tight, pretty good!
I would highly recommend.....
