Less well:
The aluminum cones are actually too small; the wax body is about 1.5-2 mm over the edge. By pressing to reduce that to between 0.5-1 mm, but the lights are then no longer plan.
For a star deduction.
Not good at all:
There was now a candle which burned completely in warmer, that is, it must be as much gas (?) Have collected that the wax surface burned, with a correspondingly large, black border, sooting flame. Luckily I noticed it quickly. Delete to let the thing just by placing another, already empty aluminum Hütchens.
I for years have pot and warmer in use without such events, I can trace the effect only to the long burning time, which could have created the time space of the gas concentration.
I will no longer buy these lights.
