I think this has been refined since some of the earlier reviews. Everything was included that you need even a basic recipe book. Every fitting was either flared with needs to be tightened with wrenches or had a rubber seal that needs to be slightly tightened once snug. Everything sealed perfectly except the drain from the condensing pot. This had a slight seap which I just let go. This connection were the copper coil meets the pot should have a nut on both sides. Not rely on the flare nut to compress against the stainless pot. If you put something behind it like a gasket then the flare won’t seal correctly and you’ll risk getting water in the product. I was very happy with the product and the price. You couldn’t think of building this yourself for this value.
