No issues. Easy to clean and functions well enough
"the hammerhead is great for reflux, but I think it's ideal to have a dephlagmator before the vapour outlet/ Liebig, as the output is quite smeared with this setup. Unfortunately no way of adding it in line at this stage. Maybe need to get a 4 port 3" column to test. The hammerhead however cools quite well and does it's part."
