This is a nice oil purifying kit, however it does have some issues.
1. The corks, while they fit, aren't of good quality and I had to enlarge the holes in them with a drill for them to fit properly.
2. The thermometer only goes up to 100C which is a bit low. The fluid inside was also split in two sections so I had to heat it up to over 150C to recombine them
3. The glass stoppers don't actually fit ANYTHING in the kit so if you don't have any other glassware, they are useless.
Otherwise, it's a nice cheap sturdy kit
