1964Ears offers the value option of not sending your impressions all the way to China and waiting for them to get back from there. It's a free not-sending-to-China service that 1964 Ears offers. Imagine if you need refits...
Of course if you live in China, then you'd probably first be considering Thousand Sounds, not UM, anyway.
ABSOLUTELY! While UM is a tempting option, having 1964 (and UE for that matter) about one day away is a huge plus. I just hope 1964 can keep their total package price low. US manufacturers are at a big disadvantage if you consider that the bulk of the cost of these things must be labor.
