Efinaconazole
"I had nail fungus in four fingernails.  Two were half lifted half off the nail bed all the way up under the cuticles.  Jublia worked great for me.  I've been using it for 5 months and they are all grown out with good nail and look great.  I'm going to stop using it shortly.  My insurance didn't cover it and I used a Good Rx coupon which got the 4ml bottle down to $243.  I was happy to pay because my fingernails looked awful."
