I've sent my order at 15th January, than I sent three letters asking about it.
They replied the first two letters very fast, almost instantly.
Though the third letter isn't got a reply yet, I just phone called them today.
I told the lady my order of livewires and my full name.
After several seconds I got just the answer I want:
my LiveWires is about to be finished in 6th February and will be shipped by FedEx.
I think sometime they might be lagged in replying with E-Mails, but calling by phone is quite efficient.
Now just wait one more week for my first custom IEM.
