Product arrived in good shape. Well packaged. I had my doubts about the seals. After the first run with water, my doubts were proven correct. The still pot seal was ok, but the thumper leaked. Silicone made in China makes me nervous. God only knows what's in that.I peeled off the seals and used canned biscuits! It works like edible caulk. Seals perfectly . Ran another pot of water to test the biscuit theory. Great results.My first true run produced more than I expected. Overall, I'm happy that I got this rig. Good introduction into distilling.
