Went ahead and purchased this little rig, with no high hopes. After receiving it and unpacking, I was immediately impressed with the weight of the unit. I expected feather weight steel, this thing actually has a bit of solidity to it. Set it up, ran a water/vinegar initial run, no leaks, worked perfectly for the full run. Next run I had a leak in the pot, stopped the run, tightened the seal, ran perfectly to the end. As long as you do not over-tighten the seals, this rig runs great. I look forward to many many more runs with great success.
