It is a good piece of equipment and I definitely recommend it to everyone looking for full destillation set for a bargain price. The joints are shaped well, I can see some minor visual inpurities both in joints (which at first little bit scared me, but then as I was using it i found no problem putting it together and using it) and flasks, but this is inevitable. I destilled a few essential oils and it worked perfectly! For those looking for a cheap heating for flasks I recommend you using an oil bath, will keep your vapours stable at low flame.
I didn´t try yet: (will update this review)
harsh corrosive materials such as acids and bases
heat over 200 celsius
vacuum destillation
