Thanks for those sticking up for me AND that read the full listing. I clearly stated that this was 1/4" copper (it's the first part of the listing!!!), which is what I had a problem with in my other thread. Some people on here are either jackasses or can't read, I just don't know which yet.
This chiller is not defective; it simply isn't as big as I need it to be for 10 gallon batches. Other people have had success with it, so I'm sure it works fine for 5 gallon batches. You also won't have to worry about poor customer service as I wouldn't want someone to be mislead like I was.
If you want a CHEAP chiller, you can't go wrong with this one (for smaller batches).
