So far I have only ran the vinager through for set up. Every thing seems good. I have a leak in the one hose it came with. My one issue is the instructions. There are terms I had to look up. I have no idea what the onion was and where to check Temp. ( No it's not the temp gauge) They don't really tell you what the temperature gauge is for or temperature to keep it at. I recommend getting a 3 gallon pond pump. It worked great after we figured out how to regulate the water flow to keep the coils covered. The leak in the hose and the instructions are my only complaint. Otherwise, for the price, compact,and easy to use, it's a good setup.
