Product review (4 stars): Made an excellent wort chiller
I purchased this tubing to make a wort chiller for brewing beer.  I'm 2 batches in now, and I have no complaints.  I made a tube bender with some soft wire (soldering wire) wrapped around the tube like a spring to help with the tighter bends, and was able to make the bends I needed without crimping or damaging the tubing.  None of the included fittings were useful to me, but it was the best price on the length of copper tubing I could find.
