In the first place, YES, good quality ear candles work wonderfully! My husband has had a long history of ear problems from excess wax, the doctors, drugs, etc. failing him for the most part. Our two sons, also had lots of trouble with their years.
We've been using ear candles now for about 25 years, with excellent results.
Also, we found that getting rid of JUNK FOOD in our diet has made us far less likely to get sick, including ear infections (which my husband and sons used to have literally ALL the time).
Last, but not least (sorry, couldn't resist the cliche ;-) my husband paid an ear specialist $175 in the early 1980s ( a fortune, especially back then!) for a few moments of his time, trying to find a solution to his constant ear troubles. That specialist told him to keep a solution of 1/2 rubbing alcohol and 1/2 white vinegar mixed up and handy, and put some into your ears each time that they get wet. It has REALLY made a difference.
Always cut a small 1-inch "x" in the center of one of those cheap/flimsy type paper plates. Put the ear candle through that so that the narrow end of the ear candle is below the plate. It works very well.
Now, with these three things, we rarely have any trouble!
