Plastic isn't the best feel on tc clamps
"Listen, they work perfectly. Strong plastic that doesn't deform or discolor (yet). And it insulates better than metal and stays cooler on the outside as a result. Allows good visibility in the column and very easy to clean (dishwasher). My only thing I don't like is tightening the triclover clamps on it. They creak without cracking, but man that makes me uncomfortable. I have no idea how far off I am from cracking them."
