Custom In-Ear Monitors?

Anyone tried buying from this website? They are called Big Ear and they offer home service for molding your ears for custom in-ear monitors and then they’ll mail the product within a few weeks. They make multiple(up to 8) transducer IEMs and that’s what called my attention. They also do have instructions for DIY molding where they’ll send a molding kit then you’ll mold your ears and send back the kit with the molds… but I guess I’ll opt out on that if ever because I don’t want to F things up. LOL! Some of their products are really intriguing and of course, I’d love to know if anyone here tried their products or maybe tried products like theirs from another store. I mean, any of you got other recommendations?

By the way here’s how they look like but based on their website they also make colored ones.
