Hard to soften and mold
First of all, these worked better than the foam ones you can buy.  I had a difficult time softening the wax and getting it to fit in my ear canal.  I must have a small canal since I cannot wear the foam ones so that makes a difference.  After a few times I got better with the placement but it took quite a lot of time to get it to where it would mold and stay in.
