I got mine at the Marloboro show last year from the HEARSafe booth. Honestly worth the wait, I debated on getting them at the Holbrook show 2 years ago when my girl got a pair, then she said how much she enjoyed them,(she has sensitive ears) I had to get a pair. They form fit in my ears, and with the baby oil, seal it quiet. I would have to say they are more comfortable than foam. I used to have wear foam and triple flange ear-pro on the range constantly, and after a while with sweat and daily wear, they would start to be uncomfortable. I can say with the custom molded one that I got, this does not happen. I shoot indoor/outdoor/pistol/trap/US Rifle. And for shooting trap/rifle the ear molds do not get in the way.
The only improvement I would make is to install a noise cancelling device like my peltor ear muffs, because sometimes I miss things because they are that quiet, but that would probably be expensive.
They do have a reputation for having the best custom fit for active CT Swat, as well as many other police departments.
