Well I've used ear candles for years on and off (don't have a very serious earwax problem)and never set myself or anyone else on fire - you would have to be pretty inept. You supervise someone else with them in rather than trying to put them in your own ears. So unless you fell asleep or were otherwise called away...
Plus they don't drip (or the ones I've used) because they aren't like normal drippy wax candles.
My niece had really bad ear wax and we used them on her - not only did it work beautifully and remove the wax gently and without discomfort, she seems to suffer less now.
You pays yer money, and yer takes yer choice...
