The larger hole in the back of the fragrance lamp is, I think, very intelligently thought out, because it is shaped so that you can put it back the already burning candle without getting caught by the thumb and to be possibly burn.
The wax can be determined by use or to change the fragrance oil removed effortlessly. I use a handkerchief or paper towel towels while the wax is warm. It can wipe thus leaving no traces.
The holes in the small ball throwing a beautiful play of light on the ceiling and walls, when the light is turned off in the room. It is a pleasure to look at the :)
Also seems to me the lamp (except at the point of the wax / oil) not to be hot. I've been a few times carried from A to B while the candle already burning for a while and she felt every time to cool. Nice not to burn your fingers!
All in all, has become a real favorite of a stopgap. Beautiful workmanship, good quality, perfect function and cleanability and for not even 8, -!
