This is probably the best distiller on the market when it comes to price-quality-features. It is very versatile with its center column, as you can even place flavored fruits or botanicals on that mesh. The bottom is doubled i believe and well built. It even has a false bottom and comes with a mesh and a bag if you really want to place solids inside the boiler and have them about 10cm above the bottom. All the valves are a nice addition as you can actually re-run your heads within the same run (just by pouring them in).
It is a good quality steel and I've look at al the solders and they look good. However you do need to clean it nicely before use, because it comes from the factory and it can still have leftovers from the soldering process.
I also want to give a big shoutout to the Vevor Support team, because while the packaging was ok (all components fit inside the boiler), all of them were protected in shipping except the Alcoholmeter which came broken (because it's made of glass and the other components must have moved around inside and stepped on it), the Support team quickly responded to the issue and resolved the issue. They were great!
