Ordered the Custom Ear-molds Impression Kit ($245). Arrived quickly but kit instructions were a bit outdated leading me to think I may have been missing some items. Called the hotline provided and left a message since they were closed. Heard back first thing the next day from Sara. She was very nice and very helpful. Turns out I was missing a pre-paid shipping label which she sent out via email to
Hoping the custom ear molds filter out race noise better than the foam or semi-custom ear buds do. making the molds is pretty straight forward but I'd suggest having a helper if possible. Would be much easier for the helper to form the material in the users ears.

Stronger Box
All items were ok, however I would recommend that the container you ship items in be stronger not as easy to collapse.
