I did a lot of research and basically the don't do what people claim. Although some people swear it offers relief. My ears were feeling congested, so I decided even if it doesn't extract earwax I would try it for some relief.
After ear candling, the first ear felt a little more congested at first and then back to normal. OMG the second ear, hot wax from the inside of the candle dripped into my ear and wasn't horrendously hot but hot enough to cause extreme pain. Now my hearing is worse off and I have a terrible earache in the second ear. I followed all instructions including the candle being straight so wax does not drip into ear. Also the first candle I put out at 3 inches and the second didn't get that far before i immediately yanked candle away after hot wax fell into ear. When examining what was left, I could see that the first candle was maybe a micrometer from falling into the other ear.
I DO NOT RECOMMEND!!!! Extreme pain and only wax in tube was from the candle.
If anyone has suggestions on pain relief for the second ear please respond because this isn't pleasant. I was able to remove some of the wax from candle out of my ear, hopefully I got it all. But my ear is throbbing as I type this. Again, I wouldn't try this if I were you, and if you have children please don't use this on them because I would hate to see what happened to me happen to a child.
